The Asus CUSL2 is a great board ,lots of good reviews,rock stable & great for overclocking,the downside it`s expensive but you are buying the famous Asus quality,the MSI MS-6337 board well I have checked their website & to be honest cannot find it listed unless it`s the new 815E board in which case it will be cheaper in price & comes with onboard sound which you may or may not like,I don`t think it`s out yet,(at least here in the UK) so you have a better change of buying the Asus board,go with Asus.
