As the title says, I'm looking for a new processor. My processor currently idles at around 15-20ish percent. I frequently play Call of Duty 4 and World at War, and multitask with iTunes, Zune, DVD work, etc. While I run these separately, my PC does fine, but when a couple of these programs are running, CPU usage goes to around 50 percent and spikes at 80. Programs then start to run at very slow speeds and occasionally crash.
My current setup:
CPU - Intel Core 2 Duo E6600 @2.40GHz
Motherboard - Intel Corp. Model OEMD975XBGG1 (I don't know all the specifics, it came with a Gateway PC around 2 years ago if that helps
Memory - 4GB DDR2 Corsair running at 800MHz
Graphics Card - 8800GT Akimbo Superclocked
OS - Windows XP SP2 (I know this causes not all of my RAM to be used; Would it be worth it to upgrade to 64bit or Vista?)
Feel free to tell me if I need to upgrade something else instead, and if I missed some information don't hesitate to ask me. Thanks for looking!
