Pureoverclock posted a review on two AM2 motherboards

Not so long ago Nvidia launched the nForce 500 chipset's for AMD's new DDR2 capable socket AM2. By now you should all be aware of the minimal performance increases DDR2 has brought to the A64 architecture and it's low latency on-die memory controller, but from my perspective the most difficult aspect of the AM2 and nForce 500 launch is leaving behind the oh-so mature motherboard choices available for s939 in place of brand new 'unproven' boards, so to speak. With that point made, anyone who's eying up AMD's recent and significant price drops across the board will be asking one question - which AM2 board will rock my world?
