Half life 2 is no doubt the most anticipated pc game of all times.

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, we measured the average fps at each resolution. The Aeolus managed to sustain a small lead over the X850XT at all tested resolutions.

With AA and AF set at 4x and 8x respectively, the Aeolus remained the dominant card at the first two tested resolutions. However, as the resolution increased, the cards were more evenly matched. Nice performance from the 6800 Ultra and Half Life II.
