PC Perspective posted a review on the EVGA e-GeForce 8800 GT KO video card

The new EVGA e-GeForce 8800 GT KO graphics card performed about how we expected it to: slightly faster than the reference 8800 GT we had tested earlier. In several cases that performance difference was as high as 10-12% on the average frame rate but in other cases the performance gap was something like 5-6%. Results obviously depend on the game title and much of its bottleneck in performance is on the shader units and clock speeds versus the memory system.
