Running an i7-2600K along with an ASUS P6P87 EVO right now and WOW!!! I, too, have been an AMD guy for my last couple rigs. I went through the recall as well and almost dumped the whole thing for a Phenom II x6, but I held off and am glad I did. Water cooling the CPU with one of the Corsair Hydro Series H60's too.
No SSD's for me, yet... down to one ODD. Encoding a Matroska file with Handbrake on it now and it will be done in less than half the time it took my Phenom II x4 940BE. About 77 frames per second vs 33 per second. I'm pretty happy with it.
