R9 280x Dual-X OC vs Tri-X OC



Tough call. I had the same dilemma and chose the Dual-X. I just didn't see the value in it. Also, I haven't seen any reviews of the Dual-X compared to the Sapphire models. Really you are comparing cooling ability and noise. I think this was one of the reasons I went Dual-X.

Vapor cools much better but that noise.
