I had not thought about that. I have one that runs at 750 and that should be good. It is almost like old dos games (v1.1) I think it was game over when they came out with the faster chips and Windows 3.1. You got killed before you could see what was happening. So much fun. I, of course, am a little slow for the shoot-um-up-bang-bang games and now my eyes are too slow for the animation especially on III. So much fun.
