I am upgrading my Server 2008 Standard SP2 x64 box (just runs SQL) and was wondering where the cheapest place is to buy a legitimate retail copy of Server 2012 Standard is? I see a lot of cheap ($200-500) copies on what appear to be legit sites, but my guess is these are OEM copies so not really legal. That said, where is the best place to buy this kind of software at the best price? Also, worth it to wait for 2012 R2 RTM instead? I don't need this server to be in production for another couple of months. Not sure when the RTM version is coming out.
