I recently changed my motherboard to an ASUS X99-A2 with a GTX 980 and an i7 5930k and have since experienced massive FPS drop in CSGO to as low as 300 fps to 100fps while shooting. I am going to test other games now. Any help and advice is greatly appreciated!
Edit: 40 fps lower in no mans sky and 50 frames drop
