I bought an iMac a year ago and would like to upgrade to a mac pro. My main use for the mac is for music production and basically all the plug-ins I use are CPU hungry. My question is, should I upgrade to a Mac Pro now or wait until the newer version of the Mac Pro comes out which is- who knows? But I am in need of upgrading quick because the iMac is definitely not cutting it and nor do I want to drop more dollars on purchasing more memory and such. Help me Mac users!
