I just finished upgrading the Celeron 520 in the Compaq 6720s to a Core 2 Duo T7700 2.4GHz. Would this be a good hackintosh for Lion? I need to be able to run Xcode at a relatively good speed, along with 1 or 2 games from Steam. The Integrated GPU is an Intel X3100. I know it's not fantastic but if it were able to run Team Fortress 2 and Portal, that'd be great.
