I run my 24" monitor at 1920x1200.
Go for it, should be a huge boost in performance.I would like to upgrade my 8800gt and get a 6950.
Usually when your CPU bottlenecked, your minimum FPS are close to your Maximum FPS, showing that its not the "graphic cards" fault, but the cpus (that you arnt getting more fps).Main issue will probably be minimum FPS more than anything else, most games are still GPU limited with a semi-decent CPU, especially at that res.
I will be ordering my GTX 570 next paycheck and running it on my 3GHz c2d system. At least until the new SB boards become available. 🙂
