Am thinking about getting a , Western Digital VelociRaptor 300GB 10000RPM SATA-II 16MB, i currently have a Western Digital Caviar Blue 500GB SATA-II 16MB. What sort of performance increase would i see, would vista, apps and games load much quicker, or isnt it worth splashin out £200?. The raptor woudl have vista, apps and games, and just keep my old 500gb for downloads and stuff.
