To add to Amoses MAC praise--the music industry pretty much has been standardized on MAC stuff for years, most of the professional software was designed to be used on MAC, so you can do what you want, recording wise, in a very stable environment--

One thing to look out for, and that is that some of the recording hardware and software may not be compatible with the newest operating systems--most solve this by either partitioning(having both older and newer operating systems installed) or simply sticking with the older operating system--
