VPC is slow for games unless they are old DOS games. Nothing 3d or whatever. Don't expect to be running Neverwinter Nights, or Half Life on it. The newest thing I was able to run on it (with some bugs) was Fallout 2. Now that it has a Mac port I don't need to bother anymore.
VPC is good to have if your into old DOS RPG's like me. I like the early Ultimas, SSI games, and Wasteland alot. But it's not like a REAL PC. My advice, save your 300 bucks and buy an old PIII or something along with your Mac.
