Well im going to go with the 9700 because I prefer ATIs products. Everyone likes what they like.
I have owned and used some Nvidia cards, even as recently as a GF2 GTS, and would be interested to see the Nv30.....IF it was going to be released anywhere close to the 9700.
The 9700 is here now. (some people have already recieved their pre orders from ATI)..I just cant see waiting another 4 months or so to find out the Nv30 is basically the same thing. The techs here now..why wait.
