Actually, I've got a Radeon 9500 (should be pretty fast...) and an Athlon 1400 (yes, one of the burning hot ones) and Planetside is majorly chunky unless I turn a lot of stuff down. I know the video card can handle it, and I've got plenty of RAM (896 MB). Therefore, processor still matters.

I am the Doctor, and THIS... is my SPOON!
