PCIE 3.0 x16 slot
Nice looking build.
I used to have an Asrock extreme4 mobo, and I 100% certain that the pcie 3.0 x16 slot is the top one, you've got yours plugged into the x8 slot, would optimize your system if you plugged the gpu into the top slot. I almost did the same thing myself, I remember thinking it was kind of annoying to have to cover up the nice asrock chipset heatsink, but I got over it.
