Actually, if you have games that are optimized for multi-processors and multi-cores you may see a large improvement since XP Pro will see both processors and all 4 cores. Since most games are very video intensive and rely on the GPU more then the CPU however, in reality, you may see only modest overall speed improvement in the game. However, I often run games on one monitor and still keep email and other programs open on the other monitor (so I can play while I am at work for stress relief from time to time) and I can still receive important emails, etc. In this case, the more processors and cores the better since the game can have all the CPU power it needs and still more is left for other programs.
