4k is 4 times the pixels (Not twice as another poster said) FOUR times the pixels, and the reality of it is that 4k is still too new to be all that gravy. Stick to 1440P and a good video card, then when it becomes more mainstream and games are programmed for it (right now you'd just be upscaling for what it's worth) You need content to make it worthwhile. Here's my take, If you're a twitch gamer you're going for frames per second, if you want the clearest picture possible go with an IPS panel, not the fastest, but the best looking right now. A good IPS panel is worth more than a crappy 4k panel. For the frames per second, get a high refresh rate panel. The 144Hz are coming down in price and beginning to gain a foothold now. If you don't need the refresh rate, get an IPS. Save the money. Take your girl (or guy, not trying to judge or guess which you are) out to the movies. 4K is the same as 1080P a few years ago, you might have the best resolution in the world, but if all your channels are in standard def, it's gonna look like crap.
