It's a nice little motherboard, I have to admit it. But beware of trying to run multiple GPUs on it. It was a pain to set it up and make it all get recognized and working.
Sometimes it would not POST, other times it would only recognize some of the GPUs. Me thinking a BIOS update would fix it, it got it completely nuked and had to clear CMOS, unplug all GPUs and start from scratch again.
I had to clear the CMOS and test so many BIOS settings until I finally got it all working right, that I'm afraid to touch it anymore.
