I found drivers for gtx 470 for vista ultimate 64bit as well as the physx card
which nvidia said BOTH work on vista ultimate 64bit. so idk what you mean it won't work on vista ultimate.
i found out it won't work on 7 tho.
also my board apperently wasn't designed natively for 7 just vista and older so i'm going with vista.
in case you need proof these cards (the physx card and the gtx 470) will work here it is...
for the gtx 470
