Considering a build using an Intel S2600CP2J and a couple of E5-2650 ot e5-2665 procs. In looking at the motherboard specs, it is not clear whether or not the board supports PCI-E 3.0 (full speed) or whether the card slot space will allow a "full size" graphics card. There is a small heat sink near the end of the video card slot that looks like it might interfere with the video card installation. I have an "extra" GTX 751 TI that would be nice to use. I'll probably be using a 850watt or 1000watt power supply so that shouldn't be an issue.
