In the PC scene they do, yes. Personally I think 4K is a bit of a stretch for gaming still. You still need to spend 3,000+ on the system for it to remotely be a pleasant experience. It's a lot of pixels to drive. The sweet spot currently is 3440x 21:9 aspect if you ask me...
As far as using it for Scorpio, I couldn't think of anything worse than using 4K at 30fps. I'd wait till the console actually drops before making a decision.
Totally agree with Mike's comments (
@Silent_Scone) about gaming with 4K currently being a bit of a stretch. I have a 27" Asus G-Sync monitor that has a default resolution of 2160x1440 - a step down from 4K. With the GTX1080 onboard, there are a couple of games that get giddy through GeForce Experience and attempt to upscale themselves to 4K. The result is dodgy looking in-game text that doesn't display clearly and the GPU now having to do a shed-load more work for little gain. The game might look a bit prettier, but for the hit in performance? No thanks.
By far a
much more rewarding experience is to pair a decent monitor, with the removal of V-Sync (be it using G-Sync or FreeSync) - then viewed in at least 144hz. It's smoothness and clarity is something to behold - really one of those 'feck - that looks good' moments you have when playing a game. The downside to obtaining this level of "WOW" is that a 1080 can cost circa £600, then the G-Sync monitor like mine will add a further £550 to that. You can see how £1,100+ has already made a big dent in the budget mentioned above.
I'd like to be impressed by the claims of 4K gaming on the likes of Scorpio - but it will definitely be one of those 'I'll believe it when I see it' things. If what
@Silent_Scone says that 4K would only be achievable @ 30fps - then I wouldn't even waste the money on a 4K TV to support it.
