I consider the CPU to be mid range and the GPU to be mid/high.
I don't want huge settings, 1440x900 resolution, 2x AA and high visuals.. It should do for most games, right?
Might be a little low on ram for the higher demand games.
Specs on GPU? What GHZ?
I have a a GTX460, its a 1gig though... and I run fallout new vegas on ultra high- with a resolution of 1680x1020 or something stupid...so that should be a good reference for you
