What games do you have trouble running then? Because I've tried several old and new games and they all work properly. Currently, I am playing Freespace 2 (works perfectly), Freelancer (perfect) and even Heroes of Might and Magic II which works great. If something doesn't work, compatibility mode usually does the trick.As I mentioned, I'm using Windows 7 at the moment. And I must say I like it much better than Vista. Though of course it has its issues with software (mostly with a few games), I haven't had much troubles or problems. I'll keep W7 for now ^_^.
