I notice some companies offering 64bit processing compatable hardware/software. Is there any realistic reason to start using 64 bit software and hardware and purchase a 64 bit computer. This is my first DAW setup that I am considering so I'm wondering if it's worth it to spend my money on a 64bit PC/Interface/Software. For example Cakewalk Sonar is releasing Sonar x64, and Mackie has the 400F which says it's 64 bit compatable. Anyone know if this jump would be worth the extra $$$?
