Ugh, I was under the impression during my research that the E5405 Harpertown was equivalent (400Mhz slower) to my current Q6600, and I would perform a slight OC if I needed to. I bought them with the idea upgrade to QX9775's later down the road once prices come down. I already bought all the parts unfortunately before I saw this thread. Wouldn't gaming be mostly influenced by the GPU? Again, I didn't go the dual CPU route specifically for gaming, just as a machine that would do everything better than my Q660/680i setup does now.
