Hey, im new, first post and i have a problem ok, my rig is in the below sig. now i have a gainward 4850, its been flashed with a asus bios by the previous owner and as far as im aware the card works ok, i ran ati tool and furmark and no artefacts found. i had a Zotac 8800GT 512mb before this but the 4850 is performing worse than the 8800GT. I have been playing games like counterstrike and have been getting lags with everything on max. Before i would get over 100FPS with everything maxed, now its only about 80 with lag. Also on Crysis, on the 8800GT i would get 25FPS on everything V.H but with the 4850 its 22 and lower in some cases. GTA4 i would get 30FPS on high settings now its only 22 with the 4850. here are some screen shots GPU-Z CPU-z stuff also my 3dmark06 score, which is rubbish, right click on image and view finally my 3dmark vantage score, the below score is mine i came across this link which someone having a Q6600 and a 4850 at stock, here are his scores http://www.soonet.ca/showthread.php?t=19754 as you can see, my 3dmark vantage GPU scores are worse than the random above users. what could be the problem???
