Should you build this?

YES, if
  • You build inference rigs yourself and know GPU quirks (VRAM, PCIe lanes, thermal envelopes)
  • You're OK with low-margin affiliate revenue at first
  • You can update prices weekly as GPU market shifts
THINK TWICE
  • Tom's Hardware, ServeTheHome, and r/LocalLLM wiki already cover this — your edge has to be inference-focused not gaming
  • Affiliate revenue requires significant traffic — slow ramp
  • Hobbyist segment doesn't pay much — paid tier conversion will be low
VALIDATE THIS WEEK
  1. This weekend: Post the comparison page in the r/LocalLLM thread (signal#1) as a top-level comment. Track clicks + saves · cite signal#1
  2. Next 7 days: Reply to the r/selfhosted multi-GPU post (signal#2) with a tested motherboard recommendation list. Measure engagement · cite signal#2
  3. 100+ visits + 10+ affiliate clicks: If 100+ visits + 10+ affiliate clicks in 7 days, expand into a full GPU recommendation site with paid tiers ($5/check, $19/mo for rig advice)

Who is this for

Budget-constrained local-LLM hobbyists looking at sub-$300 GPUs (signal#1, 29 upvotes r/LocalLLM); inference rig builders running 8x RTX 6000 Pro on Workstation motherboards (signal#2)

Bloomberg-style buyer profile · grounded in real signals

Pain · LOW

r/LocalLLM 'Best budget AI GPU for $300' (29 upvotes) — clear price-sensitive segment. r/selfhosted motherboard-for-8-GPUs post — niche enthusiast. No paid-product asks

The pain users describe: Best budget AI GPU for $300

Timing / why now: Validate first — no dated trigger. Ongoing GPU buying-decision pain in the hobbyist segment but no specific market event tied to these posts

Existing alternatives: none clearly identified yet — opportunity for a first-mover

Help me draft an MVP technical plan:
1. Core user flow (happy path, 3-5 steps)
2. Data model (main tables and their key fields)
3. Tech stack recommendation (favor fast-to-ship options)
4. First 3 things to build this weekend
5. What NOT to build in v1 (scope discipline)

1 Build a static comparison page 'Best inference GPU per $100 tier' with VRAM, FP16 TOPS, second-hand market price from eBay sold listings, model-size fit table (7B/13B/70B). Post in r/LocalLLM thread (signal#1) · cite signal#1
2 Add a 'motherboard compatibility' filter for multi-GPU rigs (signal#2 use case). Source data from motherboard specs + community-reported rigs
3 If 100+ page visitors in 7 days, monetize via Amazon/eBay affiliate links + an optional $5 'check my parts list' service
