Ti4200 is a bit faster than both the 5200 ultra and 9600 non-pro without any eye candy on. However with AA/AF enabled, the 5200 ultra and the vanilla 9600 will outperform the Ti4200. Honestly it may be in your best interest to save a little more $$$ and purchase a 9600XT for the performance is hands down quite a bit faster than either of the cards you mentioned when it comes to gaming. But to answer your question is it worth a extra $50 to get a 9600? I say no, but its right on the borderline where you can swing either way....considering price/performance anyway
