So by adding your system specs like I have below, will give other people a comparison to go by. So here's mine; Spec's; 3930K @ 5GHz HT enabled 16GB (2400MHz 10 12 12 31 2T) Running @ 2133MHz 9 11 10 25 142 1T 3x EVGA GTX 670 F.T.W+ 4GB @ 1346MHz core - 7114MHz memory (As I have flashed my cards with a modified vbios, my boost clock on standard is 1228MHz, so with the extra +120, it set the boost to 1346MHz. Also increased the power limit to 300% and Voltages to 1.215v for a real solid stable OC!) http://www.3dmark.com/3dm11/6090128
As per my signature, two GTX 670 in SLI as follows... ASUS GTX 670 Power Target = 111% GPU Clock Offset = 170MHz Mem Clock Offset = 400MHz Gigabyte GTX 670 Power Target = 111% GPU Clock Offset = 130MHz Mem Clock Offset = 400MHz This gives a clock of 1240MHz for each GTX 670 and memory of 6804MHz.
Will update this post when I get home with my results. http://www.3dmark.com/3dm11/5310826 X Score: 6337
No way I'm posting a score in here, with you lot swinging your multi-GPU e-peen around and spraying the walls with Geekosterone!
