Either the Radeon R9 270X or the NVIDIA GTX 760 (which is basically a re-branded GTX 670). I'd say wait a while until the next GPU's arrive. GTX 660ti is fine for now. If you wanted to get max settings at 1440p you would need to spend a good $300+.
@IrrelevantJohn: Actually it does but it's a bit all over the place rather than a standard as it is on the 360. For example some games run at 720p (like the Uncharted games), some run at 1080p (like Wipeout HD and Ridge Racer 7) and some run at 720p but are up scaled depending on which resolution your PS3 is setup to (Final Fantasy XIII and XIII-2). GTA IV also did this but only if you turned off all resolutions apart from 1080i/p, but it ran horribly.
