It will fit there fine, since the motherboard has one PCIe 2.0 x16 slot.
However, your motherboard is socket FM2, which means that the best you could have is AMD A10 6800K. This means your CPU will bottleneck a GTX 980, so you will be wasting your money unless you plan to upgrade your CPU and motherboard later to some platform. I will suggest you stick with R7 370 or GTX 950. That is what I will recommend.
If you plan to upgrade to a different CPU later, get the GTX 980.
