Buy a dedicated mining motherboard; they are far less likely to cause problems and headaches, both with initial setup and future stability. The Biostar TB85 is literally plug and play for 6 GPUs and out of the dozen or so rigs we have it's been the most stable overall... so I would pick that one as my first choice for Intel mining motherboards.
Thank you for your replies!
Price is a must for me now, since GPUs are my priority; so between all of these, the TB85 seems the best, even if the cpu socket is 1150, so I can't mount what I found to be a great one (the g3930).
What CPU do you suggest for this MB?
