Should be pretty decent for 4K on account of raw horsepower.
4K is still in it's infancy and as so you should probably read a bit about it before taking the plunge. Some TVs work OK with it, others don't. Some drivers work great, while others dont. If you need to do font scaling then you may have problems with some programs. Also you will probably be stuck at 30fps unless you are getting a higher end monitor. Some cables do not properly support 4K either.
Suffice to say... you can get it to work. You just may want to work off of the advice of someone who has already dont it and gotten it to work.
