I am planning on putting Ubtubu on my computer. Can i run any game i want on it or am i better off running XP and Untubu?
No, you cannot run just any windows game on Gnu/Linux.
If you aren't particually experienced with computers I suggest DualBoot since it gives you chance to get best of the both operating systems.
Now to make it clear, Wine/WineX/Cedega/TransXOffice can run native windows games on linux but usually they have lots of problems. Cedega is wine ripoff which is dedicated to run windows games on it. Usually it's the best bet and list of supported games can be viewed here: http://games.cedega.com/gamesdb/
But you could and should instead play native linux games like Return to Castle Wolfenstain, Doom3, Quake 1/2/3/4, Enemy Territory, America's Army, Unreal Tournament 1999/2003/2004/etc., Quakewars, and lots of others you can find from http://www.tuxgames.com
Some games are compatible with Linux when you buy them from store since those ship linux binaries on same cds/dvds as windows version like Unreal Tournament 2003 and 2004. Other and more common way is to ship windows version to stores and then after release of windows version publish linux binaries on game maker's website so that people who have paid for windows game can use same cds/dvds to install linux version from those.
Setting windows games to work on linux is as much work as in windows but it's bit different still and some people don't like it. Basic rule is that older the windows game is better it works.
There are many native games for linux and linux also runs windows games when spesial conditions are met but it still will not replace windows as a gaming os.
I consider myself casual gamer so I am fine with small bits of QuakeWars per week so I am bit different. But my straight and honest answer is that for gaming only linux isn't perfect yet. It needs more major commercial game support from companies like EA and Atari.
You picking up Ubuntu as your distribution is good choise I think since it's the most secure operating system on planet at the moment and probably good in many ways. But I have to be honest to say that I don't like it and I'd be ratcher running plain Debian, Fedora or openSuse. I am currently in love with Gentoo Gnu/Linux (I've been couple years for now) which tells about my background something.

Point of that was that if you don't like Ubuntu, try something else. Linux isn't like Windows where if you don't like something you cannot change that bit. In linux you can change that bit and that's the reason there might be 15 different Adobe PDF readers if you don't like first reader try next reader or you could make your own reader if you prefer.
