I'm seeing a weird artifact in SLI with a pair of GeForce 7600 GTs. It's like a flickering green fringing effect on certain pixels on the screen. Sometimes there are puple-colored pixels doing the same. Sometimes it's kind of subtle, but other times it really jumps out at you. The problem appears to be related to an image from the secondary card not making it over 100% intact to the primary card somehow. I tried to take a screenshot, but the artifacting doesn't show up in screenshots.
My basic test setup is like the one here:

So far, I've tried to eliminate it by swapping things out, hardware-wise. I've tried:
-Two sets of 7600 GTs
-Two different driver revs (91.31 and 91.47)
-Two different copies of the P5N32-SLI SE Deluxe mobo, each with its own Core 2 Extreme X6800, 700W PSU, and 2GB of RAM
-Three different SLI bridge connectors
The image artifacts remain with any of these configs. This problem doesn't affect G71-based 7900-series cards on the same setup.
The only way I've found to eliminate the fringing artfact is to shut down, remove the SLI bridge connector, and boot back up. Running without the connector, the image looks perfect. Of course, that hurts performance, which isn't acceptable for testing.
Have any of you guys seen this problem with SLI and G73-based graphics cards? Any ideas for a possible fix?
