That's pretty strange, I made the exact same decision last week. I decided on the PB278Q because in reality, 1440p is the only way to stress my 2 780Ti's. I have to say the color accuracy is tremendous, its totally worth having 2.5x more pixels than 1080p is you want the premium gaming experience. My 2 780Ti's keep me around 75-80 FPS even on Crysis 3 high settings. With so much GPU horsepower it's pretty much a no-brainer for me.
