Hey, I'm new here and wanted to ask a couple of questions; I built a working setup with the Akitio Thunder 2 PCIe box and powered riser with my MBR late 2013 15" back in late Dec with: core i7 4850HQ quad core @ 2.30 GHz GT 750M dGPU 512TB SSD with Win 8.1 Pro UEFI boot EVGA GTX570 SC stock cooler edition 480 Watt Logisys PSU with paperclip method I have finally had time to use it again, however, I found that I am having stability problems after I updated to the newest nvidia driver (350.12); Any game or 3D intensive application will crash after around 1 to 2 mins of game play. I reverted back to the last working set of drivers, 347.99, and it seemed to work. I noticed that the GTX670 was not stable in your build, and I wanted to see if anyone else had tested the 570.
