Edit: It looks like it does affect the performance. I lost 2k in vantage.

This is with my GTX 260s in slots 1 and 3.


and this is with them on 1 and 2



Also, when I put the cars on 1 and 2, the responsiveness of the system was pretty bad too. There was a lot of stuttering in vista. I have 4 raptors in raid 0+1 seagate+1 DVD drive all on the MCP with 1.55V. Considering that the middle slot is connected to the MCP, the MCP might require more volts if you have something like me(with all 6 sata ports occupied).
Thanks for doing that for me, that provided a lot of great information!
I took a look at my board with a flashlight, and it looks like I am the cause of my problem. It looks like I may have damaged the board when installing the video cards, there are a few scratches in the PCB right where the video card mounting tabs notch into the case. It looks like I took out some ciruits going to the 2nd and 2rd PCI-e ports. It looks like I'll be stuck with one video card until I get a different board. Thinking about trying out the EVGA 790 FTW. Maybe I'll use my SE2 for some Dry ice runs to practice.
