i started with vista when it first came out and nvidia and vista just have problems and still have massive problems, i started using xg drivers click here (download section) i have always been delighted with them, never had a single problem, everything seems crisper and faster. i use the 64 bit ones now, courtesy of a small registry tweek. where did i find out about them? nvidia forum! last signed driver update for 8800 cards was nearly 5 months ago, and every beta seems to have a fix for one thing and a break for another, but hey, spend a mere £400 and you shouldnt really expect any driver support! rant over.. 174.93 are about the best you will see IMHO.
