A titan x can handle 4k decently. Normally 60 but may drop at times, while it may not be ready for 5k people who dont own titan x's needed to stop spreading misinformation
You don't need to own a Titan X to know what the published results show or that, in gaming, the 980 Ti is often faster, due to its 30+% OC ability, ....
both struggle in today's games to deliver 60 fps @ 4k. I quick bit of research / reading will show that.
Titan X (Techpowerup)
Watch Dogs - 43.6
Tomb Raider - 56.4
SoM - 52.0
Ryse - 42.1
Metro LL - 28.0
FC4 - 37.2
Dragon Age - 39.9
Dead Rising - 29.4
Crysis 3 - 28.2
BF4 - 38.8
AC Unity - 31.4
That's 11 games outta 19 (58%) where it can't do 60 so that kinda goes against "normally 60". Fully 47% had trouble even doing 40... and that's average fps not minimum. Most gamers definitely do not enjoy playing at average 30 fps especially when minimum fps is far below that. 144 Hz gaming at 1440p w/ a G-Sync card using ULMB at 85Hz is a far more smooth and enjoyable experience than playing at 4k and 30 fps. And we're talking about planned purchases here.... so we have to expect the system to stand up for 3 years.
As for image quality, tho long in the camp against using IPS panels for gaming, panels released in the last year have changed the landscape completely. Today's panels, thanks in large part to 144 Hz and ULMB have eliminated the response time issues and, to my surprise, the old "IPS Glow" in low light conditions has become a thing of the past. You can't even take advantage of ULMB until you get to above 60 hz
As for photo editing, whether you will benefit from accurate color depends on your goals. If I want to use a pic in an instruction manual any old TN 6 bit panel is fine. In AutoCAD, having accurate colors is immaterial as long as one, for example, can distinguish between blue, red, brown and orange which are used in the drawing legend to distinguish between utility lines. But if doing color portraits ... my son minored inn photography and he started out on a TN panel(which he used for gaming) but soon bought a IPS panel as facial tines were extremely difficult to "get right" on the TN.
The Titan X is certainly a great option for both gaming and editing usages but no GFX cards available today are ready for 4k gaming in today's AAA games ... and the % of games for which you can't get over 60 will only continue to grow. 5k makes it all the more of a problem.
