I've had a V3 2000 and a Viper770 in my machine for the last few months in order to get the best performance and quality. The TNT2 just plain sucked at glide games (Unreal....) so I had to keep the V3. Well I just bought a GeForce SDR and UT looks awesome!! Now that I have a GeForce, do I still need to keep the V3 in my machine in order to best play old/upcoming glide games or can I get rid of it?
