OK, so I am adding another GPU and turning my 580 to a physx card and I am getting a 690 I was gonna get 2x 680's but i think a 690 is a better idea now which one msi, evga, asus, xfx? Im leaning towards the evga and asus reasons why my 580 is a evga but my motherboard in a asus rog board so I love both companies but which one do I want to give 1200 dollars for a gpu.
