Are you thinking about buying one?
If so how much have you got to spend, that way i am sure that someone will be able to point you in the right direction of what card to get..
If you like games then my advice would be not to get any of the lower range card's ATI 9200, FX5200
Well 2004 will be a big year for games.
Half life 2 and Doom 3 out, they both are going to require some hefty kit to get them looking like they should. The cheaper cards that you mention will be able to cope, but very poorly.
So if you say how much you are willing to spend then we can help a bit more....
