🎯 The AI Workload Target Metrics
Edists clarification to goal machine
Yes—this is a capable local-AI desktop plan. But the description oversells what 16GB of GPU memory can do. The biggest thing to settle is the GPU, not the CPU or case.
First: name the actual graphics card
Your combination of Blackwell, 16GB GDDR7, and approximately 1,800 AI TOPS matches the NVIDIA GeForce RTX 5080. Its actual memory interface is 256-bit, with 960GB/s bandwidth. It is a high-end card, but not the flagship—the RTX 5090 has 32GB VRAM.[nvidia +1]
So replace:
NVIDIA Flagship Desktop GPU — Blackwell Architecture Tier
with:
NVIDIA GeForce RTX 5080 — 16GB GDDR7, 256-bit memory interface
That turns marketing language into an actual component you can price and compare.
The AI performance claims need correcting
“8B models fit at full unquantized precision” is not a safe promise
At FP16/BF16, model weights require roughly two bytes per parameter. An 8B model therefore needs roughly 16GB for weights alone, before the conversation’s KV cache and runtime overhead. NVIDIA’s own example puts Llama 3.1 8B’s unquantized weight memory at 16.06GB.[developer.nvidia]
For a 16GB card, the sensible target is quantized 7B/8B models, leaving room for context and runtime memory—not an assurance that unquantized 8B models fit comfortably. Quantization reduces weight memory, while longer context still increases memory requirements.[developer.nvidia]
“65+ tokens per second” needs a benchmark attached
That figure is not established by the specifications you pasted. You would need to name the model, quantization, inference software, context length, and test conditions. NVIDIA’s 1,801 AI TOPS rating is a hardware capability figure, not a measured chat-generation speed.[nvidia +1]
I would remove the promise until you have a benchmark for the exact setup.
64GB system RAM does not turn 16GB VRAM into an 80GB GPU
Software such as llama.cpp can split work between CPU and GPU to run models larger than available VRAM. That is CPU/GPU hybrid inference, not a unified high-bandwidth GPU memory pool.[amd]
That makes larger quantized models an option to experiment with, but “can load and run” is different from “runs at a speed you’ll enjoy.” I would describe 32B/70B support as conditional on the model format, quantization, context length, and offloading configuration—not a blanket compatibility guarantee. Those variables directly affect memory needs.[developer.nvidia +1]
What I would keep—and what I would qualify
Component
My assessment
Ryzen 7 7700X
Keep it on the shortlist. An eight-core, 16-thread CPU is a reasonable supporting processor here; the unresolved question is how much of your budget remains for GPU memory.
64GB RAM, 2 × 32GB
Keep the capacity target. It supports the larger-model experimentation you described, without pretending to replace VRAM.
DDR5-6000 CL30
Good target, but not guaranteed plug-and-play speed. AMD officially rates the 7700X for DDR5-5200 with two DIMMs; EXPO is memory overclocking. Choose a tested kit and validate stability.
Reused Samsung 990 EVO 1TB
Keep it in the plan—you already have it, so there is no need to buy storage simply to complete a new-parts checklist.
B650 motherboard
Keep either candidate on the shortlist, but choose an exact board rather than leaving alternatives in the final bill of materials.
1000W PSU
Treat this as a purchasing specification, not a completed selection. Confirm the exact model/revision, ATX standard, and included GPU power cable.
Air cooler and mesh case
Sensible direction for your straightforward air-cooled tower. Check the exact GPU dimensions, cooler clearance, and RAM clearance before ordering.
The keep/qualify decisions above are my assessment of your proposed build, not a completed compatibility certification.
The decision that matters most for your goal
For local LLMs, I would compare GPU memory capacity before paying extra for the headline TOPS figure. NVIDIA’s lineup includes 16GB cards at several performance levels, while its comparison table lists 24GB on the RTX 3090 and 32GB on the RTX 5090. More VRAM can let you keep a larger model—or more context—on the GPU instead of relying on offloading.[nvidia +2]
That does not automatically make a used 3090 the better purchase. Price, condition, power consumption, warranty, and your intended models still matter. But it does mean a 5080 is not automatically the best local-LLM choice just because it is newer.
A more accurate goal-machine description
An air-cooled local-AI workstation built around an NVIDIA GPU, Ryzen 7 7700X, 64GB DDR5 RAM, and a reused 1TB NVMe SSD. With an RTX 5080 16GB, the primary target is GPU-resident quantized 7B/8B models. Larger quantized models can be explored through CPU/GPU offloading, with performance and memory requirements depending on the model, context length, and software configuration.
The overall plan is good. I would finalize the exact graphics card and total price before calling it the final build—and remove the unquantized-8B and guaranteed-speed claims.

Why I’d price it there
Xencelabs currently lists the original Medium bundle with Quick Keys at $264 new, discounted from $329.99. That makes $175 a meaningful discount while still giving you credit for the like-new condition and included accessories.[xencelabs]
However, an Amazon search result advertises a matching-looking original-generation bundle at $149.99. I couldn’t verify the exact offer or availability from that result, so treat it cautiously—but if buyers can actually purchase the same complete bundle new for $150, you’d likely need to price yours around $110–$125 to compete.[amazon]
My starting move: $175, buyer pays shipping, reasonable offers welcome. That assumes this is the original Medium model, not the newer v2.
Profit and loss
so how does it look with the 10% take from mercari – for all of this –
and compare it to the cost fo the goal machine?
Selling all 10 would give you roughly $1,500–$2,000 after Mercari’s 10% fee, before shipping-related deductions and packing costs.
That is a substantial desktop fund—but the RTX 5080 version of your goal machine currently looks closer to $2,665–$3,250 before tax. The GPU’s current price is the biggest obstacle, not the rest of the tower. Recent retail checks put available RTX 5080 cards around $1,900–$2,200 rather than their original $999 starting price.[ign +1]

The laptop’s $250–$350 and watch’s $25–$40 ranges are placeholders for this budget calculation, not researched valuations. The printer’s range also remains provisional because it is unused but untested.
The upper total assumes everyone pays your asking price. I’d budget around $1,700–$1,800 in proceeds rather than spend against the full $1,993.50.
Mercari’s shipping wrinkle
Mercari charges its 10% seller fee on both the item price and buyer-paid shipping—not just the item price.[mercari +1]
So the table is a simplified item-price calculation:
• If buyers pay $200 in shipping across the listings, another $20 comes out in seller fees.
• If you offer free shipping, the shipping cost itself comes out of your proceeds.
• Boxes, packing materials, and any separately purchased coverage also reduce your fund.
Several of our descriptions say “tracking and insurance included.” Make sure those promises match the shipping option you actually choose before posting.

The practical takeaway
Your clutter can fund a meaningful AI-desktop budget. It just doesn’t currently fund that exact RTX 5080 machine outright.
The key distinction is:
• At a hypothetical $999 GPU price, the same component allowances put the tower around $1,764–$2,049 before tax—much closer to your sale proceeds.
• At the recently reported $1,900–$2,200 GPU prices, the card alone consumes approximately your entire sale fund.[ign +1]
I would sell the gear first, treat about $1,700 as the working fund, and choose the exact GPU against real available prices rather than lock yourself into the 5080 name. I’ve also included the proceeds spreadsheet as a CSV so you can adjust the sale prices as offers arrive.
shit!!. Recent retail checks put available RTX 5080 cards around $1,900–$2,200 rather than their original $999 starting price
we can’t get anywher near the 2250 goal then.
how long is this price gougoing going on for ? forever?
Not necessarily forever—but there is no reliable end date, and I wouldn’t promise you that waiting a month or two will bring the RTX 5080 back to $999. NVIDIA has acknowledged supply constraints, and recent reporting still shows sharply inflated prices.[ign]
And yes, that is frustrating: the same build changes from achievable to out of budget without becoming a better computer.
What’s actually happening?
It appears to be more than individual sellers marking cards up. Recent reporting points to limited GPU availability, strong demand, and memory shortages. A late-October survey of several US retailers found the cheapest available RTX 5080 offers starting around $1,980.[notebookcheck]
However, shortage reports do not establish a date when prices will normalize. Nvidia’s 5080 and 5090 marketplace categories reportedly returned by November 2, but both remained out of stock—so a store listing reappearing is not the same thing as affordable supply returning.[pcmag]
Does that mean years of these exact prices?
No one can establish that from the available evidence.
PCMag reports a memory supplier’s expectation that broader memory shortages could persist through 2030. That is not a forecast that an RTX 5080 will cost $2,000 until 2030. It is a wider supply outlook, not a price guarantee for this particular card.[pcmag]
The honest distinction is:
• A return to $999 soon: not something we can count on.
• Prices staying at today’s level forever: also not established.
• Waiting a fixed number of weeks and getting a predictable discount: no reliable basis for that promise.
Your $2,250 goal isn’t dead—the exact 5080 build is the problem
Using the non-GPU allowances from our budget, the rest of the tower costs approximately $765–$1,050. That leaves:
$2,250 before tax
$1,200–$1,485
Total budget
Available for the GPU
$2,250 including tax
Less than that, depending on checkout tax
Those are planning figures from our earlier estimate, not current checkout quotes.
So you’re not suddenly unable to build an AI desktop. You’re unable to fit a roughly $2,000 GPU into that particular budget.
My recommendation: keep the $2,250 ceiling and make the GPU negotiable—not the other way around. Don’t pay nearly double the original starting price just to preserve “RTX 5080” on the parts list.
Also, I should have checked actual GPU availability before presenting that card as a realistic goal. Catching it now is better than after you bought the supporting parts, but it should have been checked earlier.
The corrected buying strategy
For your project, I would:
- Keep the $2,250 total ceiling.
- Compare the 5070 Ti against the 5080 for your intended 7B/8B-class work.
- Compare a tested 24GB used card if running larger models matters more than maximum small-model speed.
- Select the supporting CPU, motherboard, and PSU after choosing the best-value GPU—not spend the budget protecting an unnecessarily rigid parts list.
You’re absolutely right: if another card delivers the experience you want for less money, that’s the machine to build. The goal is a useful local-AI workstation—not owning a particular model number.
well – what gives us a simliiaer experies to the goal machine – and let’s see thje costof that –
then we can decide what we can live without?
The closest sensible alternative is an RTX 5070 Ti 16GB build: keep your Ryzen 7, 64GB RAM, and reused SSD, and reduce GPU speed rather than GPU memory capacity. A realistic planning total is approximately $1,885–$2,205 before tax—not the $2,665–$3,250 estimate for the inflated-price 5080 build.
There’s also an important correction: this lookup found lower advertised 5080 prices than my earlier blanket $1,900–$2,200 range. The retailer data is inconsistent, so we should treat these as advertised offers to verify—not guaranteed stock.
1. Closest to the goal: RTX 5070 Ti + 64GB RAM
The 5070 Ti preserves the original machine’s 16GB GDDR7 capacity, Blackwell architecture, fifth-generation Tensor Cores, and NVIDIA software ecosystem. NVIDIA specifies 1,406 AI TOPS versus the 5080’s 1,801—but those figures do not translate directly into a percentage difference in chat speed.[nvidia +1]

Budget
$1,885–$2,205
The GPU range is supported by Best Buy’s advertised $1,149.99–$1,249.99 listings. Newegg search results advertise a 7700X/ASUS B650E bundle at $314.99; the PSU and case figures are consistent with approximately $140 and $116 listings. The RAM and cooler figures remain budgeting allowances, not verified checkout quotes.[bestbuy +3]
For an illustrative 9% sales-tax allowance—not a verified tax rate for your address—the total becomes about $2,055–$2,405. That puts the lower-to-middle part of this plan within reach of $2,250.
What the experience keeps
• The same VRAM capacity as the original goal, so you retain broadly the same model-weight memory budget. Context and runtime overhead still matter.[nvidia +1]
• The same NVIDIA/Blackwell feature generation, including FP4-capable fifth-generation Tensor Cores.[nvidia]
• Your 64GB system RAM and eight-core CPU.
• GPU-resident quantized smaller-model use, with larger models explored through CPU/GPU offloading rather than pretending they fit entirely in 16GB.[nvidia +1]
What you give up
Some GPU throughput—not model intelligence. Running the same model with the same quantization does not make its answers worse merely because the GPU is slower. The main tradeoff is how long computation takes; the exact difference needs a matching-model benchmark rather than a TOPS calculation. NVIDIA’s inference-sizing guidance distinguishes model memory requirements from compute and performance requirements.[nvidia]
I would not promise “only 10% slower” or another specific figure from the evidence we have.
2. Cheaper option: RTX 5060 Ti 16GB + the same supporting machine
Best Buy advertises an ASUS RTX 5060 Ti 16GB at $788.99. Replacing the 5070 Ti with that card puts the same supporting build at approximately $1,524–$1,744 before tax, or about $1,661–$1,901 with the illustrative 9% allowance.[bestbuy]
16GB VRAM
Lower GPU performance tier
64GB system RAM
Longer waits should be expected; exact differences need workload benchmarks
Ryzen 7 7700X
No CPU downgrade
What stays
NVIDIA-based local-AI setup
Less emphasis on maximum speed
What changes
This is the budget fallback, not my claim of an equivalent-speed machine. It preserves the memory-capacity target while spending less on processing performance. NVIDIA’s comparison table distinguishes the 5060 Ti’s processing specifications from those of the 5070 Ti and 5080.[nvidia]
3. The original 5080 build might be less distant—but the price needs checking
The Best Buy page I retrieved advertises:
• ASUS Prime RTX 5080: $1,599.99.
• PNY and Gigabyte RTX 5080 models: $1,699.99.[bestbuy]
That conflicts with the higher-price reports I previously relied on. The retrieved page also contains outdated pickup dates, so I cannot honestly call these confirmed available-to-you deals.[bestbuy]
At an actually purchasable $1,600 GPU price, the supporting build above would total approximately $2,335–$2,555 before tax. Still over your ceiling, but considerably closer than I made it sound.
What I would cut—and what I wouldn’t
For the 5070 Ti machine, NVIDIA specifies 300W graphics power and a 750W required system-power recommendation. A good 850W PSU therefore offers a sensible alternative to your original 1000W target, subject to the exact card manufacturer’s requirements.[nvidia]
My priorities would be:
- Keep 16GB VRAM.
- Keep 64GB RAM initially, since larger-model experimentation is part of your goal.
- Use a less expensive suitable motherboard, rather than paying for a particular premium board name.
- Use a good 850W PSU instead of insisting on 1000W.
- Keep the reused SSD and straightforward air cooling.
- Choose the 5070 Ti before dropping to the 5060 Ti if the final checkout total fits.
The 5070 Ti build is the first one I’d try to land: roughly a $2,100–$2,250 all-in target with disciplined parts shopping, while preserving the original machine’s 16GB GPU memory and 64GB system memory. The 5060 Ti version is the lower-cost fallback if you decide speed is the compromise you can comfortably make.
