The difference is that the 3000 series introduced 12 Core CPUs that weren't available before AND provided increased gaming performance. This time around the major reason seems for upgrades to be single core performance - which I guess as they didn't really go into multi core performance. But we'll know more when the benchmarks come out, and discussion beforehand is pretty pointless.
