EDITED FOR BENCHMARKS: 1200 Core, 1375 Memory 3DMARK11 Top Score Overall - P11787 http://3dmark.com/3dm11/3402572;jsessionid=rys4f3hqon2u1t31fq6zdwbp7 3DMARK11 Top Graphics Score- 13677 Update May 16th Woke up this morning to more stability issues after leaving the PC on all night, running stock.. I have RMA'd the 2nd card and am sending it back. Sticking with the one original card, this has really turned me off from Crossfire... and I'm happy with the performance of one card overclocked. (Plus my original O/C's much better) I was about to pull the trigger on a single 670, but after much thought, I've actually been very pleased with the performance of my original 7850 and just decided to sit on that. Sorry for the back and fourth, but its packed up and being dropped off today.
