First info on NVIDIA's GeForce 9600 GT (D9M) has shown up on various tech websites. I like DailyTech so I'll post a link to their article on the 9600 GT. <click here>
An NVIDIA representative is reported to have said that performance of the 9600 GT is almost double that of the 8600 GT. Heh. Considering how poorly the 8600 GT fared in a lot of reviews I'm not sure that is as impressive as it sounds.
In any case, I'm more interested in info on D9P and D9E than D9M. I expect we'll be hearing more official info about NVIDIA's 9000 series graphics cards come February.
