I have upgraded my personal computer during the black friday sales and was thinking of turning it into another 6-8 card mining rig.

The specs on that machine are:
I5-4670k or (I3-4130 <--spare)
8gb DDR3-1600
MSI Z87-G45 Gaming MB

Has anyone had any experience with this motherboard? or would you sell off the system and by newer hardware? I was curious because it has 7 PCI-E slots. I would most likely run SMOS for the OS.
