well may I recommend some hardware for you to check out , a favourite motherboard seems to be the asus p8z77v series 1155 socket and it’s also used by some mods for testing and as the latest i7 processor is 3770k it’s well suited and that bundle with the corsair 32 gig or ram will suit all you needs . The reason im recommending this build is because now the new 2011 socket is becoming more widely available the 1155 setups are getting cheaper and cheaper so I decided to build the exact built myself im just waiting for the 3770k to turn up and im all systems go . Im 100% sure you wouldn’t need to upgrade for a few years
Edit
sorry and I do know quite a few people that do run this system with win 7 64 bit and they do run perfectly once they have been optimized for music production
