Hello, I am presently trying to figure out what will give me the most bang for my buck: the OLD Viper 2M VRAM, or the NEW Viper 2M VRAM. I believe the only differences are that Weitek component and the price. I could buy a brand new Viper with Wtk 9100 for $350. But someone is offering me a Viper 2M VRAM with the Wtk 9000 for $125. Which one do I go for? I'm into 3D Animation, and I need raw power… Thanks!
