RTX 5090 doubles to $6,899 as RAM prices eclipse GPUs in worst-ever PC build market

- Yuchen Jin (AI2 researcher) notes the RTX 5090 now costs $6,899 — double its price a year ago — and quips: is everyone hosting local open-source models, or did someone figure out how to train frontier models on gaming GPUs?
- He previously pointed out that a single 256GB RAM stick now costs $1,400 more than an RTX 5090, calling it the worst time to build your own PC.
- AI-driven demand for GPUs and high-capacity memory is pushing consumer hardware prices to extreme levels.
