if you still get problems with your game you will have to think about a upgrade as this old card is really showing its age now and its lack of support for later open GL and pixel shader is showing.
good cheap cards are everywhere on ebay now nvidia 5600 upwards and ATI 9800 upwards both will keep you going for about another year before they bring out bigger better games
