Benchmarks Results

3DMark05

The EVGA GeForce 8800GTX KO beats the reference design GTX model by 450 marks at 1024x768 and by almost 950 marks at the maximum pixel resolution of 2560x1600. The Foxconn GeForce 8800GTS beats the reference design (XFX card) by 750 marks at 1024x768 and 550 marks at 2560x1600. We see a similar correlation with image quality turned on.
