What DO you want to spend?
There are a ton of cards in several different price ranges, so you're better off setting a budget/price range before you even start looking at them. If you're looking for the best bang for the buck, you're probably going to end up spending around $100-150, which will get you a very decent card. Of course, as with everything computer related, no matter what you get, it will be obsolete as soon as you touch it....so, does it really matter?
