Need some help. I just purchased a Compaq Presario SR1000T computer and a got the 256MB DDR ATI Radeon 9800 w/ TV-out & DVI Cap. I don't know a lot about cards, but I know I wanted a powerhouse so I can play Half-Life 2, Doom 3, The Sims 2, etc, etc. Is this card a good card, or did I waste my money. Also, is there a major difference between this card a 9800 PRO? I appreciate any replies.
