Radeon 9800xt

So basically my 9800xt is a piece of crap.  It overheats all the time, ruins games, and shuts down my system every once in a while.
Now, what I am asking you guys is what is a good graphics card I can replace this with.  Nothing too expensive, but I can do like $200-$300.  Also, would like a graphical improvement over my current graphics card, and certainly more stability/less overheating.  Thanks ahead of time.

or if you're a fanboi of ati then get an x800xl(t) from like Frys and bribe someone 10 bucks to give you a manager discount or employee discount
