The HD 5000 series across the board does a good job of making games playable at certain resolutions. If you're a resolution fanatic then the HD 5870 or HD 5970 is going to be the best card for 2560 x 1600 users. Are you mainly a 1920 x 1200 user? Well, the HD 5850 is a great option and if you're not a huge gamer but you like to dabble a bit at the resolution, the HD 5770 does a pretty good job of holding its own.
