I don't know, i have heard the ti4200 is better than the radion 9000pro. However, i got my radion 9000pro 128mb ddr for 50 bucks after rebat from frys and when playing counter strike, or americas army, mine looks better than my friends. ANd he has a similarly configured system with a geforce ti420064mb. I can esily get 70+ fps on both games and my friend spent quite a bit more than $50 bucks on his graphics card.
