I am going to be receiving my 2.8GHZ octo core mac pro with the NVIDIA 8800GT on Monday. I will be installing XP via bootcamp on the system to play games. I plan on running everything cranked up to high includding 8X AA and 16X AF. I will be playing on a resolution of 1280 by 800 (1/2 of res. of 30" ACD). I heard that people have been having problems with lowering the resolutions on their APPLE CINEMA DISPLAYS! Has this happened to you? Please help. Praying that all goes well on my new Mac Pro.
