Just bought a new Nvidia 8800 GTX Graphics card and fired it up for the first time a couple of days ago. I got a higher 3Dmark '06 score with this single card than with my 2 X ATI XT1900XTX's in crossfire. Trouble now though is that after making a minor BIOS tweak last night to disable the secondary PCIe slot, the machine now takes ages to POST and the score for my new Nvidia card has dropped to about a quarter of the first benchmark. I have tried this now with the secondary slot enabled and disabled to no avail. When I slot my ATI's back in, the PC runs as it should. I haven't edited my signature yet but a brief summary of my Rig: AMD FX60 @2.6ghz DFI Lanparty CR-DF 200 2gb Samsung DDR Polit Geforce 8800 GTX 768mb @ 1800mhz. 3Dmark '06 score : 9104.
