Hello,
I have recently bought and installed a second matching graphics card. I've installed all the latest mobo/graphics card drivers (started with fresh OS) but can't seem to run bf3 in high without crashing. Single GPU ran fine on a different motherboard (ASUS M5A97). I've tried modifying my settings based on other users complaints for the same problem. I've even tried previous versions and beta build mobo/gpu drivers/bios with no luck.
I'm wondering if I have a power bottleneck. Here is my build (I don't overclock):
AMD Phenom II X6 1055T
Gigabyte GA-990FXA-UD3
2x4GB G.Skills DDR3 1600
2x Gigabyte Nvidia Geforce GTX 550 TI in SLI Dual 16x PCIe on mobo
My PSU is a 650W Corsair TX650 V2 with specs found here:

What do you guys think? Do I need a bigger PSU or is something else at fault?
Here are some stand alone temps/voltages/etc:

Any help is appreciated. I believe I still have time to return the GPU and Gigabyte mobo if they could be the cause. I will get temp/voltage readings while running bf3 now...
