If your running XP32 bit you could go up in ram a bit to 3gigs if your running the 64 bit xp got to 4 gigs. You could go up to an x4 proc essor also but I dont think you would see a ton of improvement.

aznshinobi, I was looking at your $1000 build and I was surprised to see it included an SB i5-2500K. I agree with that, but it's a pain to find a motherboard nowadays.

OP, your CPU can handle a lot more than a 5770 in gaming, btw. You could probably use a 5870 if you wanted (and your PSU, case, etc. accommodated for it). But you may need to OC a little.

Budget for this upgrade is 300ish dollars it will be filled in a bout 1 to 2 months and i am goin to get windows 7

If you or someone who uses the computer is a student, get the Student Windows 7 for $30.

You want to make sure your CPU can handle whatever upgrade you do (Use 15% Capacitor aging): http://extreme.outervision.com/psucalculatorlite.jsp

And you probably want a 5850 or 5770.

EDIT: My estimated wattage requirements assuming OC'ing, future HDD, and all other factors...
5770--410W
5850--460W
5870--515W
6970--600W
A 5850 would probably be fine with your current PSU if you don't add other hardware or overclock your graphics. A 5870/6950 would probably be fine if you did no overclocking and no additional parts.
