Hi. I just got a new Macbook Pro and I want to put windows on it so I can play Call of Duty 4 but I just have a few questions. 1) Does Windows XP or Vista work better? 2)Will my computer run it and at what settings? Here's the specs: 2.2 Ghz Intel Core 2 Duo Processor 1440x900 resolution 2 Gb RAM 120 Gb Hard drive NVIDIA Geforce 8600M GT with 128MB SDRAM Thanks for your time and I would really appreciate your reply.
