You know, I keep seeing this said, and while I'm not the exact definition of what you just said, I've been seeing the basic concept of this argument over and over in this thread. (no one games 1080P on a 1080 GTX) And yet, here I am, about as close to that as you can get without actually being 1080P.
1080 GTX STRIX, 3960x (OC'd to 4.4 to 4.6 depending what I want at the time), rampage IV, 16GBs of RAM
And a Samsung 1920 x 1200 monitor with almost zero inclination to upgrade the monitor at this time.
All of it, except the GPU, was singled out and bought by me in 2012. So, the GPU got upgraded and the monitor didn't and likely won't for a while. It happens.
