Half-Life 2: Episode One
The GeForce 7950 quad-SLI doesn’t bring any performance improvements in Half-Life 2: Episode One, either. Yes, the performance of a single GeForce 7950 GX2 is enough here to play in 1920x1200 with enabled 4x FSAA, but you don’t need a second card for that! Moreover, the GeForce 7950 quad-SLI is about 20% slower than the Radeon X1950 XTX CrossFire in 1920x1200.
The quad-SLI platform does better than the Radeon X1950 XTX CrossFire in SLI AA 8x/Super AA 8x mode, yet this is not crucial because both the platforms provide a comfortable frame rate in every resolution, including 1920x1200.
The ATI platform still makes all the resolutions playable, but Nvidia’s GeForce 7950 GX2 quad-SLI system cannot deliver a comfortable frame rate in 1920x1200 with enabled 16x SLI AA.
