I currently have NVIDIA GeFOrce FX 5500 256mb but i was wonder if an ATI Radeon 9200 128mb is better because that is what i used to have installed, but since i reformated and installed the Geforce with more ram, i have been getting lots of problems. My fps went down, and my computer will freeze for about 20 seconds for no reason, and sometimes it will completely crash. I tried updating drivers. But it hasnt done any good. Any suggestions on what to do and which card is better?
