Dual RTX 3090 fit sparks LLM debate

The interesting part here is not NVLink itself but how much local AI builders still optimize around used 3090s because they remain one of the cheapest ways to get serious VRAM at home.

• –The post is about physical fit and cooling, not model quality or software capability
• –Dual 3090 setups stay relevant for local inference because 48 GB combined VRAM is still attractive for hobbyist and prosumer LLM work
• –Founders Edition card thickness makes bridge spacing and motherboard lane layout a bigger issue than raw GPU availability
• –This reads as community troubleshooting, which is useful context for self-hosted AI builders but weak as a standalone news event
