i just installed a 4850 today, moving up from a 8800gts, no more stutter in shat... 35-45fps in shat, which the 8800 couldn't get near.. love the card... and the picture quality is better than the 9800gtx's i have sold.. no suprise there though

The only downside to the card is that it comes stock running the fan at 27% which had me at 80c... i bumped it to 50% and am at 40c with 700 clock
