How do Macs, and specifically the 2.4 MBP with the 256m 9600GT play these types of games? Am I going to be OK?
When buying a game, obviously a PC game is going to show PC specs? How do I compare those to running Win in Bootcamp when deciding whether my MBP will be able to run them?
The specs should be virtually the same so long as you're using Boot Camp. The new line of Mac's are basically identical to Windows systems with one minor exception: Windows system still use a BIOS while Mac doesn't. Just look at the specs on the box and if your computer meets them you're good to go.
