I'm looking to build a new gaming PC and wanted to get some CPU suggestions before I placed my order. I've always been an AMD fanboy but want to build an Intel system this time. I don't really know anything about the Intel processor lineup so I've just been looking around at different CPUs. Is the Core 2 Duo E6850 the best dual core that intel has out at the moment? Would I see an increase in gaming performance by going to 4 cores over 2?
