Standout
Nvidia GeForce RTX 5090 (32GB)
32GB GDDR7 — runs 70B-class models quantised on a single card

Nvidia GeForce RTX 5090 (32GB)
The fastest consumer card available, with 32GB of GDDR7 — and the power bill to match.
Where it wins, where it doesn't
Pros
- 32GB GDDR7 — runs 70B-class models quantised on a single card
- Fastest consumer silicon available
- Avoids the complexity of a multi-GPU build
Cons
- Roughly double the 5080's price for far less than double the performance
- 600W-class power delivery dictates case and PSU choices
- Poor value for anything that is not memory-bound
