New GTX 460 setup - help please.
I just installed a new motherboard (Gigabyte GA-990FXA-UD5) and a second GPU (both Palit GTX 460 1g OC editions) and i'm running into all sorts of issues when I try to run the second card in the other 16x slot. It only seems to work in the 8x slot, and even then still has issues when I try to run Unigine Heaven, or any other kind of benchmark. I can run Crysis 2 with all settings to max with the high res and tessalation packages installed @ about 70-95 FPS. I'm not sure what the issue is at all anymore. I've updated the BIOS and every other driver I can think of (unless I missed something) and I'm truly at a loss.

If I try to run both cards in the 16x slots sometimes the computer will only be on for a minute or 2 before it crashes or the GPU's just stop working. Here's what I'm working with.

MoBo: Gigabyte GA-990FXA-UD5
CPU: AMD Phenom II x4 955 3.2Ghz
RAM: 2x 2Gig corsair DDR3 XMS
PSU: Corsair 650W (Can't remember the model for the life of me, I'll check and edit the post when I get home)
GPU: 2x Palit GTX 460 1g OC edition
HDD: Western Digital 1TB eSATA drive
OS: Windows 7 64bit

If anymore info is needed to help me out I'll gladly post it, this problem is insanely frustrating.
Thank you in advance to any help and suggestions.

EDIT: The guys at Tom's Hardware have pretty much solved the problem for me. Looks like I'm buying a new PSU.
