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

This weekend: Post the comparison page in the r/LocalLLM thread (signal#1) as a top-level comment. Track clicks + saves · cite signal#1
Next 7 days: Reply to the r/selfhosted multi-GPU post (signal#2) with a tested motherboard recommendation list. Measure engagement · cite signal#2
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)

I want to build a tool 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)

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
