Hello. Although I have an adequate gaming PC, I am considering either buying a new box or overhauling this one. Currently I used an ATi Radeon 9600 pro, I was going to upgrade, but it seems every week theres a new ATi card on the market. Even though I am not computer illiterate, I still stood at Best Buy staring at 3 different ATi cards that according the the box had all the same features....yet had different titles and prices. Basically I would like someone to give me a hierarchy of ATi cards from best down to the 9800 pro. I would be much obliged for any help. Thanks!
