I play it alot, so I would say it is worth it, but I am an avid UT player. My opinion may not be what you are looking for. Try the demo beta. If you comp can run it with everything all the way up the game looks great. If not, it can run well on just about anything, but it will look terrible on lower end machines. (if that matters to you, just thought I would let you know) Hope this helps!
Best,
