So I am trying to get my gigabyte 280x's going and I am using the following config

-v 1 -w 256 -I 12 -g 2 --lookup-gap 2 --gpu-powertune -20 --temp-target 73 --temp-overheat 85 --temp-cutoff 90 --gpu-memclock 1500 --gpu-engine 1000 --thread-concurrency 8191

GPU 0 runs is basically not hashing

No clue whats going on.

Reboot fixed it...
