I read both tom's and anandtech, and they said nothing about a 256 version. There may not be one. I wouldn't say there won't, but nothing points in the way that there will be. I am interested in how the NV5700 does in respect to the ATi cards. If it is very close to the desktop card, it can beat out all the ATi cards. I still will prolly go NV either way just because of driver support I can get with my drivers.
Either way this is a good point for AW people who bought the new 51m to laugh at anyone who gave them hard time about getting an AW and how thier X-band lapotp is better becuase they got X card. We can atleast upgrade ours to the best, while they are stuck with what they bought.
