Q: particularly for use in a recording studio FL studio, protools, reason etc
A: Depends on what you are using it for and if all the cores are being utilized. My guess is not many apps will take advantage of a quad core chip but you may be using one of them. If so then no dual core will out-perform it. If it is for games then I think most new games will take advantage of dual core and a quad core chip will be wasted.
