The 6600GT won't run applications that require Shader Model 3 at a playable framerate, so it really makes no difference. People say that it will run it at 30-40fps. Well as I said, that is not playable. 72+ is playable, and 60 is bearable. And BTW, there won't be anything that REQUIRES Shader Model 3 for a long long time to come. Everything will have SM2 fallback. There currently no games that need it, but there are two I know of that have the option of using it. the first is far cry, and the second is half life 2:lost coast.
