Fear doesnt run well on ATI cards?!? I dont know, im in the process of downloading it, but its sponsored by ATI, I thought. HL2 runs better on ATI cards and it is sponsored by ATI, I thought that was how it worked.
and yes, considering its price, the X850 XT Platnum, is not as good as comperable Nvidia cards, but you can get the X850 XT PE on tigerdirect, like I did for half the price as the top of the line nvidia cards...
