Hey guys! I'm considering upgrading my iMac to a mac pro using my ADC discount late this summer. I have to have a Mac for my major, as I use a lot of OSX-only programs. However, when looking at all the benchmarks available for the programs I'll use, it seems that half do better with the higher-clocked 2.66 4.core, and half do better with the lower-clocked 2.26 8-core. I'm a pretty big gamer, and so if I'm buying this computer anyway, it'll probably be replacing a PC as my "gaming rig." And, so, I'm thinking of letting that be my deciding factor. Now, I know that the workstation processors aren't meant for gaming. But, that's not my question. What I'm wondering is, while it seems 99% of games out right now prefer a higher clocks to anything else, would it be wise to purchase the 8-core (thus, even more cores than the currently underutilized 4-cores) model to future proof my system for gaming? Other than GTA IV, will we start to see games in the next year or two that really start pushing 4+ cores? Thanks!
