Just look in the OC thread, most of those guys are damn near 4GHz.. the Anandtech article on the C2D more or less pointed out the same.. the 6600 is the CPU they see as the gem of the bunch. Once more ppl get them and start to OC and post results, there should be a better idea of what CPU will be the better choice but I am going by what I have read so far. *shrug*
