I had a Gigabyte GA‑970A‑D3P but realized that it only supports 32GB of RAM, so I was looking for a MATX board(so I could get a smaller case) instead and found the AsRock 970M Pro3 which supports 64GB of RAM, I've been playing two games the most recently one being SpinTires, the other being Portal 2 , I used to have solid 60 FPS in both games(with my original mobo), but now it dips down as far as 40-ish FPS with the new mobo, so I was wondering if I'm bottlenecking or something. (my specs are: GPU:EVGA GTX 960 SSC, CPU:AMD FX-8320 RAM: Crucial 2x 8GB)
