Hey guys this weekend I purchased a second 670 2g ftw and sli'd them. I then ran a 3d mark test and felt kinda nervous with the results. I scored a little over 12k. Everyone else I have seen running 670s sli'd are getting 14k plus.computer specs are as follows. Any information or ideas are greatly appreciated. Asus crosshair formula v-z, 8150 amd bulldozer oc'd to 4.4, 16 gig corsair vengeance 2200, lsu ultra 750 watt sli ready bronze cert psu.
