Hello guys. I've been fighting with my new GTX680 card that would sum up to GTX680 SLI. 1 x Gigabyte GTX680 2GB 1 x Palit GTX680 2GB First of all I had trouble with the installation since I couldn't get SLI enabled. Finally I solved that problem which was due to that I probably didn't push the small extra power pin (6+2) to the Palit card which oddly enough requires 6+8 pins and not 6+6 like my Gigabyte card. My next problem is that all games I've tried so far in SLI mode look worse than with SLI disabled. The colors look washed out, almost 8-bit at times and the screen constantly flashes (not much but enough to be annoying). This flashing effect is most noticable on dark surfaces vs light. Also GPU-Z says one card is running at PCI-E x8 version 1.1 and the other one PCI-E x1 version 3.0 even if a game is loaded and running. The Gigabyte card worked flawlessly when alone and the Palit card works well too if SLI is disabled at x16 version 3.0. Palit is currently GPU1 and Gigabyte is GPU2. What the hell could be the problem here?
