The Geforce FX 5200 Sucks, get rid of it, quick. Trust me, I have horrabile experences with it.
It crashed a lot, I.E.: I could do something for 3 minutes, it would crash. I had horrible frame rates, My old Radeon 7500 is FAR better then the pice of **** that i had. If you want to get the most bang for your buck get a Radeon 9600 like i have now. I have a reletivly old computer (Specs: 1GHz athlon t-bird, 512 MB ram, 40 gb hdd, ect...) and i can play UT2K3 with HIGHEST DETAIL at 1024x768x32 with absoute lowest frame rate on any map of only 15 FPS, but the avrage is 40 and the high is 80FPS when looking at the floor
