Hello all, I have a quick question regarding what cpu and mobo I should purchase next. I primarily use my pc for gaming; bf3, Skyrim, assassins creed, d3,and so on. I have 2x6950's crossfire with a 955be phenom. However the cpu is a bottleneck and I want to upgrade to a Intel core. I just don't know if the 2500k is still good and wi last me a while or or if I should go with the new ivy i7. Also, what new motherboard is excellent for crossfire. I have about 500 to spend.
