NVIDIA to Counter Radeon HD 6970 ''Cayman'' with GeForce GTX 580

[Carfax]

As long as Cayman has good minimum frame rates, that's all I care about. Haven't bothered with 5000/GF100 cards (waiting for next gen) but from what I recall isn't Fermi much better than the 5000 series at minimum frame rates at identical resolutions/settings?

I would much, much rather have a card that runs something at 1920x1200, max details @ 50FPS average with 35FPS minimums than something that does it @ 80FPS average with 20FPS minimums.

Yep, Fermi is noticeably better than the 5000 series when it comes to minimum framerates; especially in multigpu.
