I have a 4 year old midrange PC that could use some new hardware but it ran Portal 2 like a champ. A textured, layered atmospheric game, Portal 2 is simply one of the most visually striking games of this year. Replete with the same kind of epic scope Crysis 2 had, Portal 2 is far more painterly in its vision.
The following screens were captured on a 1.8 GHZ dual core, with 6 gigs dual channel DDR2, ATI 3850HD and running Windows 7 64-bit at 1680 x 1050, settings at max with 4x MSAA and 4X AA.
Note the levels of detail on the surfaces, the textures and the lighting
