I've got a 2.4 GHz Core 2 Duo 17" MacBook Pro. Hi-res display, 2GB of RAM. Should be fine for running graphics-intensive 3D games. How is XP running via Boot Camp working for the really intense games? The one I'm most concerned about is Half Life 2. I've got HL2 and HL2: Episode One already, and I'm pretty much decided on preordering the Orange Box so I can get Episode Two, Portal, and Team Fortress 2. I just want to be sure that it'll run well enough before I commit. Thoughts?
