If you sit even remotely close to a display that big, you're going to be able to see the pixels very easily. Your display becomes 'Retina' (i.e. unable to see the pixels) at 50 (4 feet 2 inches) inches away, with a PPI of 68. I personally was uncomfortable with a PPI of 89 at about 18 inches (1.5 feet) away from my old monitor. It may be better if you buy a higher resolution 60Hz monitor instead if you need such a big display. What will you be using this monitor for, on what PC specifications? There's no use buying a 144Hz display if your PC can't handle it.

144Hz isn't going to make a difference for coding and movies. For gaming it will, but a higher resolution display will make a far larger difference at that screen size.Your PC isn't anywhere near powerful enough to maintain 100+ FPS on high quality settings at 1080p. Unless you plan to upgrade your GPU to at least a RX 480 or GTX 1060 (preferably a GTX 1070), you won't benefit from the higher refresh rate. A 7950 isn't going to be able to maintain acceptable frame rates at 1440p either, so it's best that you stick to a normal 60Hz 1080p monitor if you aren't going to upgrade the GPU any time soon.
I think its better for you to go with VX3209-2K monitor if you plan to use for Coding / Photo editing or Video Editing and less amount of Gaming.Or even a Dell 2K monitor will be better with better quality. Each type of application needs different type of Monitor.
