Tweaked 1P Sandy Bridge processor (i7-3960X and i7-3930K) performance is something to behold. They are beginning to displace older 2P+ systems, such as the top of the line 2P 2010 Mac Pros, even those with the 5690X processor swap, for top Geekbench 2 scores. These new SBs are yielding Geekbench 2 scores in excess of 27,000. What is even more amazing is that the i7-3930k can be had for under $600 and a pair of 5690X processors will set you back over $3,000 or five (5) times as much. These tweaked SBs yield Cinebench 11.5 scores in the 13 to low 14 point range. They have comparably priced Xeon equivalents for those needing ECC ram support - Xeon 1660 and Xeon 1650 -> More bang for the buck!
