Wondering if i can play at 2560x1440 with my current setup

i am planning to get an achivia shimia monitor that is 2560x1440 but i dont know if i can run it. i have a anthlon 455 at 3.6 ghzs and oced 6950 2gb. i want to be able to run most games at med to high setings with a minimum of  30 fps avrage. if i can not run it what should i upgrade, the cpu or the gpu?  

depends on the game, but the 6950 can easily handle most games at that res on med or high


You should be able to at most games in different settings. The resolution actually relieves bottlenecks caused by the CPU.

thanks. its good to know that my cpu won't bottleneck my gpu at that res
