If it is the Gainward GF3 Ti 200, jump on it. You can overclock that card to Ti500 levels, and the improvement from the GF DDR to the GF3 will blow your mind. I've got that with a system that is otherwise almost identical to yours. I play AH at 1600x1200, 32bit color, and my frame rate never goes below 50 - usually 65 - 75.
