Here are my specs:
Gigabyte Z87X-OC with Intel® PentiumTM G3220 and Kingston 8GB 1600MHz DDR3 Non-ECC CL9 DIMM (2x4) as a base.
As hashing units I am expecting 4 MSI AMD Radeon HD 7950, 3072MB, GDDR5, 384bit to be delivered as we speak.
All this will be powered by one Sirtec - High Power PLUS GOLD 1200W - arrives on Monday... I hope.
I actually opted for this MB because I have no way to easily procure riser cables... from China they will arrive somewhere from 9 all the way to 29 of Januarry
Have phun
Can you please make some picture of Your rig?
I like this MB, and probably i will use it too without risers in this case.
