Hmm I'm waiting for 6 cores of joy. The pros are too few at the moment. the hyper threadding reimplimentation seems nice but the speed diffrence between the quads and i7's of the same price range and stock setup to me dosn't justify the outlay. My q6600 un overclocked is still don't 95% of every thing for me. when I over clock it to ~3ghz it usually adds another 4% onto that as well

so for me the cost is pointless for the rewards. if an i7 cpu becomes $~200 I might look at it as an upgrade option but not when ddr2 is so cheap at the moment. having 8gb of ddr3 will be a tad costly for the diffrence in performance.I wonder what the cost of a core 2 quad xeon is? they have hyper threadding in them if people just want that.
