But I'm not sure if this motherboard will take the two video cards in the PCI-Express 2.0 slots because it says "(1x, 4x)" next to it. Does anyone here know what that means? Will I be able to run the two video cards at their full speed?
If not, does anyone have a suggestion as to which motherboard would work for my requirements?
The board that I was considering (2nd attempt, ASRock H77 Pro4-M: http://www.newegg.com/Product/Product.aspx?Item=N82E168...) would not have worked. I ended up calling EVGA about the video cards. So basically, the video cards need at least an x16 slot with PCI Express 2.0 x8 speed. So I needed to find a motherboard with 2 PCI Express 3.0/2.0 x16 slots that both can be at least x8 speed.
It's not much, but for the slightly more L3 Cache (6MB vs 8MB) and clock speed (3.4GHz/3.8GHz vs 3.5GHz/3.9GHz).
As of today, it is a $110 difference. And to be honest, it's not that worth it. But for the next step up, it's the E3-1280V2, which is 0.1GHz more for $300ish more. Then it's the E3-1290V2, which is another 0.1GHz more for another $400ish more. So I guess I decided to stop after the $110 jump.
