I've found a great price on a 4K monitor. Obviously, you need like 5 980's to run anything decently at that resolution. I'm going to most likely use SLI 970s, so I would probably game at 1440p most of the time. I've heard by almost everyone that whatever your monitor, you should run any game at the native resolution. How bad would a game look at 1440p, or even 1080p on a 4K monitor? The only reason I"m even considering it is because of the price, it's like $450.
