techPowerUp posted a review on the Mad-Moxx 7900 GTO 512 MB Burstfire

Mad Moxx has been providing pre-modded cards to their customers for several years now. Their GeForce 7900 GTO Burstfire is a GeForce 7900 GTO, overclocked to 7900 GTX speeds. In our benchmarks we saw that performance is identical to the 7900 GTX, at a much lower price. What makes the Mad Moxx product special is that you retain your warranty and the GTX overclock is tested and guaranteed.
