I'm considering an upgrade from my 15" Pbook G4 to either a 17" Macbook Pro or 24" iMac. One of the options on the MBP is the high res screen. How exactly does that affect gaming? So far, my understanding is this: 1. Higher resolution requires more system resources (lower FPS). 2. Assuming you have the system resources, higher resolution looks better. I'm still a little confused about how all these variables interact. Can you have a 1920 x 1200 screen and lower the resolution for games, or will it not like running on a non-native resolution? If the only games I anticipate playing are MMOs like Lord of the Rings Online and Warhammer, should the MBP be fine playing at high resolution?
