I dunno. Cause' if you get 120fps in css with a 8800gts. and 130 with a 2900pro.... You probably don't have the "uber l33t OMG precision instincs" to notice the difference..
But who cares, I mean I would milk those 10 more fps for all the bragging rights they were worth.
well i'm still kinda hoping and leaning on the whole wait til ati gets better drivers out.. i'm hoping that'll fix alot of things... this nvidia ati battle seems to be one of drivers and not hardware
