Half life 2 is no doubt the most anticipated PC game of all time.

Characters - Advanced facial animation system delivers the most sophisticated in-game characters ever seen. With 40 distinct facial "muscles," human characters convey the full array of human emotion, and respond to the player with fluidity and intelligence.

Physics - From pebbles to water to 2-ton trucks respond as expected, as they obey the laws of mass, friction, gravity, and buoyancy.

Graphics - Source's shader-based renderer, like the one used at Pixar to create movies such as Toy Story® and Monster's, Inc.®, creates the most beautiful and realistic environments ever seen in a video game.

AI - Neither friends nor enemies charge blindly into the fray. They can assess threats, navigate tricky terrain, and fashion weapons from whatever is at hand.

To measure performance we used the Video Stress Test(VST) that is available in the CounterStrike:Source beta available through Steam. We set all the details to the highest level and each time changed the resolution from 800x600 up to 1600x1200.

With AA and AF settings off, all cards reported extremely high framerates, with the ASUS N7800GTX TOP slightly better.

With AA and AF set at 4x and 8x respectively, the ASUS N7800GTX TOP seems not to be affected. 135fps at 1600X1200 is quite impressive, 40fps more in comparison to the 6800Ultra and the X850.
