Half-Life 2: Episode One
Our testbed’s CPU proves to be the bottleneck at the resolution of 1280x1024 pixels: all the graphic cards deliver the same speed. There are some differences at 1600x1200, but they are not critical, at least for the three versions of GeForce 8800 GTS, each of which provides a comfortable speed. The same is true for the resolution of 1920x1200 pixels. Despite its high-quality visuals, the game does not need a lot of graphics memory. The GeForce 8800 GTS 320MB is a mere 5% behind the senior (and much more expensive) model that has 640MB of onboard memory. The pre-overclocked GeForce 8800 GTS from MSI takes second place behind the GeForce 8800 GTX.
Although the GeForce 7950 GX2 has better results than the GeForce 8800 GTS at 1600x1200, you should not forget about problems you may encounter with this graphics card, which is in fact a SLI tandem, and about the much lower quality of anisotropic filtering the GeForce 7 series provides. The new solution from Nvidia has driver-related issues, too, but its problems are more likely to be corrected than those of the GeForce 7950 GX2.
The GeForce 8800 GTS 640MB is no better than the GeForce 8800 GTS 320MB, perhaps owing to the game’s running on a modified Doom 3 engine and is not very hungry for graphics memory. Just like with Ghost Recon Advanced Warfighter , the increased performance of the NX8800GTS OC Edition makes the resolution of 1920x1200 quite playable. For comparison, the ordinary GeForce 8800 GTS offers the same speed at 1600x1200 only. The flagship of the series GeForce 8800 GTX is beyond competition.
