It's 32bit, so far I've tried Homeworld 2, Empire Earth, NFS Carbon, C&C Generals, only NFS worked (under 98/ME compatibility ) but for a limited time only. Now it crashes after a few minutes Chess and Inkball are good so they keep me entertained. Drivers are also new, I'm going to upgrade a few parts soon maybe my pc isn't powerful enough to run that system and a largish game at the same time
