Just curious what kind of card I could get away with for SCII with everything on ultra @ 60fps. I don't want to skimp out or settle for a cheap card that won't do the job, but I just want to know what is the absolute most inexpensive card to allow everything to be maxed out. Thanks for any opinions.
Price/Performance wise the 5870 is the all around winner in terms of the settings you'd like to play. It just so happens to also be a winner in most other titles out there with the same requirements and for the same reasons (and will cost you less on your power bill by a noticeable amount too).
