98% of the games in Mame will play just fine with this setup. However, it's those games you just mentioned that might have a couple issues. *Might*, I said. I'll be curious to see how you fare as well. In fact, my purchasing decision is hanging on how you fare. I've got a cab set up for fighters, with a 450MHz board right now, and of course I can't play any of them as it's far too slow.
