Far Cry 2

Far Cry 2 produces the same picture as Crysis: the graphics cards with 512MB of onboard memory slow down in the difficult test modes. As a result, the Radeon HD 4770 CrossFireX tandem wins the easy modes but can’t cope with 8x full-screen antialiasing and 16x anisotropic filtering. The same goes for the Radeon HD 4770 and HD 4850. The two GeForce GTS 250 with 1 and 2GB of memory don’t suffer such a performance hit and do not fall far behind the senior models. The GeForce series wins in the top price segment.

X3: Terran Conflict

The Radeons beat the GeForces in X3: Terran Conflict. CrossFireX technology works well, and the Radeon HD 4770 tandem wins this test. Take note that every graphics solution ensures a comfortable frame rate in every mode and at any resolution in this game.

Left 4 Dead

The Half-Life 2 engine this highly popular game runs on has always been favorable towards Radeon GPUs. This is true this time around, too. The red team wins in every segment although the difference in the bottom segment is negligible: the Radeon HD 4770, two GeForce GTS 250 and Radeon HD 4850 are close to each other, and even the slowest of them can ensure a comfortable frame rate at every resolution. Therefore, the HD 4770 is the optimal choice for playing Left 4 Dead and there is no point in paying extra for a faster card.
