Mad Shrimps posted a review on the Asus Extreme N6600GT SLI

Asus has been around for 20-years, this success is most likely based on their steadfast loyalty to the PC-Enthusiast in all of us. Today we built a "budget" SLI rig running two Asus N6600GT Extremes based on the NV43 GPU which fully supports their 256MB GDDR3 memory compliment. Mated with an Asus P5ND2-SLI the system can handle any 3D-title and definitely put the fun back in performance.
