So, I'm upgrading my PC (Or, rather, winging this one out the window and starting fresh) and am having trouble deciding on a new CPU. I'm going with -ASUS Crosshair V AM3+ mobo, -2x HIS ICEq Radeon HD 7970's in Crossfire -4x4gb Ripjaw G.Skill DDR3 1600 RAM -Raidmax 1kw modular PSU I'm going to also pick up a corsair h100 watercooler most likely, so OCing is possible. I can't decide between a Phenom II 4 or 6 core processor, or the Zambezi 8150 8 core. The Zambezi is the current flagship, and is definately appealing; but I hear that it lags in certain applications and doesn't handle multiple GPUs well. Anyone out there have some knowledge?
