Shader count, and shader clock. You need a MINIMUM of 32 shaders. But optimally you want at least 96 as a minimum. The higher the better. But you really don't see much improvement past the GTX275.

Awesome! Thanks, now how do I find out how many shaders they have? I can find out the Shader Clock stuff on Newegg.com's detailed specs, but I can't find their Shaders...
