I'm doing a build for my dad and need to get a budget video card for him. I'm thinking in the $50 range. Problem is, I know almost nothing about cards in the sub-$150 range. He'll probably doing some photo editing with it, and it needs to run Aero without any hiccups. He'll be hooking it up to at least a 22" screen, possibly 24", and there's a possibility that he'll be hooking a TV tuner up as well. What's a good video card in this price range that would fit his needs?
