I have the MBP 13" version before the most recent update in April of this year. My specs are: 2.26 GHz Intel Core 2 Duo (processor 1, Core 2) 4 GB 1067 MHz DDR3 Nvidia Geforce 9400m 256 Mb VRAM My question is can I run games such as Doom3, Quake, Left for Dead, or CoD4 on this system without too much choppiness or lag?? How playable will it be? -and is it better to run games FOR Mac (such as COD4), or do they run better through Win Boot Camp (whatever that is). Thank you for any and all input on this subject.
