I have a quad 5770 gaming rig/desktop and I love it over the other options per dollar. Cards are 55-65 each, so that 260 for the worst.
Bf3, MW3, Skyrim, NFS: The Run, La Noir, ....you know, I have yet to find something I can run on ultra.
How is LA Noire? I almost bought it on super-sale yesterday, but then I realized I haven't played skyrim or the old republic or bastion or any other game I have acquired in the past year...
