Just purchased a new iMac 3.06ghz Nvidia 8800 GS. I know there are a few posts similar to my question (mine is slightly different). I'm running Vista and graphics on demos I've played are terrible. I have read people recommending to d/l the lastest drivers for the 8800M GS. I went to laptopvideo2go and tried to download their files. So far I keep getting the Nvidia installer saying "cannot find hardware..." Does anybody have a quick step by step for how I can get this up and running?
