I've heard good things about the graphics on ATi cards. (By the way thanks for the compliment, and yes I still watch the Simpsons... great show. It's there for my daily laugh and with satellite, there's about 10 episodes per day!!) One tip about buying cards, they do go out of date pretty quickly, so you should only buy what you need. For example if you don't need too mcuh power a R8500LE or Ti4200 should be fine. Unless you have loads of money to burn, don't buy cards for their bragging rights, that usually leads you to poor decisions. Also if you think you'll be playing more games or doing some video editing, maybe think of getting a more powerful card if you can afford, it although I'd say a Ti4200/R8500/LE is enough.
My firewall tastes like burning.
