I'm not familiar with the ASRock 970EX4 enough to say that it can run five GPUs. Check
this out for motherboards that may work.
cryptokeeper...I was wondering if the ASRock 970EX4 and Intel Celeron G1610 Ivy Bridge Processor, would be able to run 5 GPU's on windows 8?
I was using your 6GPU setup from your site, but after reading your post and seeing as your only using 5 GPU's I figure I should opt to buy the cheaper mother board and just run 5 as well. Thanks
