All these people replying saying "4K isn't worth it, you need too much horsepower" with either Titan X's or 980 Ti in SLI in your signature, WHY on earth would you spend $2K on graphics to play at 1080p or 1440P???
What a colossal waste of CASH!!
There is no WAY you would not be able to run most game @60FPS at 4K resolution with specs like that.
BTW, the cost of a 4K monitor is being grossly exaggerated in this thread, I just picked up the Acer XB280HK G-SYNC for $500 for my *lowly* single 980 Ti.
You guys need to get your heads out of your butts. 4K is not the future? 4K is a waste? This is tech advancing! Jeese, so much negativity about a resolution that will soon become the standard.
"You offend by bringing up things I can't afford" GTFO outta here, man. PC gaming is very much pay to play. If you can't afford 4K, then don't buy 4K man. NO ONE CARES WHAT YOU HAVE AND DON'T HAVE AND NO SENSIBLE PERSON WOULD EVER SHAME THOSE WHO DON'T HAVE THE LASTEST AND GREATEST!
4K is great and is here to stay, so what if current GPUs have trouble pushing the pixels? Its new tech soon to become current tech, get over it. New tech always has a price premium.
I get the "I need 120/144 Hz man", but I don't understand "60 Hz makes my eyes hurt and is poverty spec" argument. If you really believe 144Hz will put you at the top of the leaderboard every game then so be it. Everyone needs to calm down and take a breath.
Some people man...
Reasonable points, I think.
I gave my "monitor history" earlier. When HD had already established itself, I picked up a budget-priced Hanns-G -- more for use with my HTPC-functional system before I went for a "real" HDTV. It was the most god-awful short-lived and relatively crappy 1080p monitor I could get, and it seemed "just fine" until it crapped out after a year as a desktop monitor, and I revisited old "customer-reviews." I replaced it with a BenQ XL-2420Z gaming monitor (1080 but 144Hz) as a stop-gap choice, because there are more considerations I need to accommodate than just UHD : I'll want to upgrade and replace my KVM box, for instance. Which graphics card or card(s)? I resolved that.
"Need" in its most severe usage might better be applied to something like gasoline or home-heating oil -- it is something you can't do without. You have to put steaks in the freezer. You have to buy clothing. You have to have a roof over your head.
Somebody might "need" 4K because of certain computer applications. After that, I'd agree that it's "subjective."
So does this addition of "Beauty" seem worth it now, in terms of opportunity cost applied to other things one just wants? I suppose that's the crux of it.
You're also right, the prices are already dropping. Again, that's no less a relevant factor: How much do I want to pay now or later for extra resolution?
I won't criticize someone who wants (or needs!) dual $1K Titan cards. Obviously, if you get such items, you almost "need" a 4K monitor -- no . . freakin' . . . doubt.
But the stats sort of speak for themselves. Getting to the point of being "left behind" in tech-obsolescence is going to be a slow, lazy journey.
