Performance in Third-Person 3D Shooters
Just Cause 2
The new GeForce GTX 580 is almost as fast as the Radeon HD 5970 at 1920x1080. The difference is also small at 2560x1600 whereas the bottom speeds of these two solutions differ by a mere 1-4 fps, depending on the resolution. Thus, each card is suitable for playing this game, but the Radeon HD 5970 is going to be far more comfortable for your ears.
Lost Planet 2
It's like what we saw in Call of Pripyat: the GeForce GTX 580 in the lead, leaving the Radeon HD 5970 far behind. Well, the GeForce GTX 480 is also faster than AMD's dual-processor card, thanks to higher tessellation performance. The upcoming Radeon HD 6900 series may change this situation in favor of AMD as it is going to feature a better tessellation unit than the Radeon HD 6800, yet it will have a hard time competing with the 16 PolyMorph engines of the GF110 processor.
