I like 4870 quad crossfire, it's pretty powerful in the games that make use of it, but it's certainly pricey, and also only really necessary for 2560x1600. Its use for 1920x1200 is a little odd, at 1680x1050 is laughable. I'd spend the money on a bigger monitor rather than a second card because at that res you just don't need it.
