I don't game or doing anything graphically strenuous. The hardest it gets used is for Lightroom, Photoshop or Sketch. I mostly code though. I have both the Reference GTX970 and Reference 7970 (flashed) but wondering which is better to keep? The only reason I think I should keep the GTX970 is the power usage being lower and the 7970 being the boot screen. I originally bought the GTX970 to drive a Dell 5K screen which I've since sold (too yellow for my liking, compared to an Apple LED Cinema Display).
