Half-Life 2
A similar story to Far Cry here. Performance at 1600x1200 is the same as at 1024x768, suggesting that SLI'd 7800 GTXs wouldn't be of much use in this particular instance.
Half-Life 2's engine is far more responsive to the subsystem than most modern games. That's why a GeForce 7800 GTX needs to be paired up with an ultra-fast gaming CPU if it is to really shine. ~100FPS at 1600x1200 4x AA 8x AF isn't bad, we suppose.
