I would also like info on your 6 gpu setup. I have ordered 2 MSI 990FXA-GD65 V2 hoping to populate 6gpus without to many issues. If this Mobo does not work looks like the MSI Z77A-GD65 is in my near future.
Can anyone confirm the version 2 board will work I see above the normal version works with no problems. But they didnt state enviroment.
Seeing yours looks stable you mind sharing. Also what PSU you using?
