Benchmarks: Quake 4, Prey
Quake 4 is usually a Nvidia favorite though at 1600x1200 with high-quality FSAA & Aniso settings enabled the Radeon X1950 Pro was actually the victor. The X1950 Pro was actually 8% faster than the 7900GS if you will believe that. However, through overclocking the 7900GS was able to produce 8% more performance than the X1950 Pro giving it a rare victory over the Radeon.
Prey is another game that typically favors Nvidia-based graphics cards as it is based on the Doom 3 engine. However, this being the case I was again surprised to find the Radeon X1950 Pro knocking off the GeForce 7900GS at 1600x1200 with high-quality FSAA & Aniso settings enabled. Here the X1950 Pro was 4% faster than the 7900GS. However, once overclocked, the 7900GS hit the lead by 6% giving it another rare victory over the X1950 Pro.
