I currently have two monitors and a mount for them taking up a ton of room on my desk so I am looking to upgrade. I have a 980 and would like to upgrade to a minimum of 2k with a single 27inch display without breaking the bank too much. Suggestions on some under $450 would be nice. Looking for image quality over refresh rate so no TN's please. Also would running 4k native and down scaling to 2k for gaming cause any problems?
