Which one is going to give me better performance? Mostly I'm just planning on doing single monitor high FPS gaming so I want something that can challenge the 144hz of my new monitor. I do eventually plan on dipping my toes into 3D gming but it's not as important. It will actually be a 7970 and a 280x but they have the same exact cooler. I'm not sure if the variation will cause any difference in performance but that's why I'm asking the experts. =D
