Lost Planet	Source: Capcom

This fast-paced third person shooter takes you across the vast and frozen landscape of E.D.N III. The ability to fight stealthily on-foot or from within heavily armored Vital Suits offer two unique modes of game play. While on foot, use the zip line to get to strategic enemy annihilating vantage points and discover unexplored areas and weapons. Or, jump into our vital suit or hijack an enemy Snow Pirate's VS to go head to head with enormous and more powerful Acrid foes.

Lost Planet framerates are about as good as you can get with a single videocard, going with something "higher end" will not make much of a difference.
