How many microseconds faster will that make my Word files when I page up and down?
zero. Word is a single-threaded application and would only use one of the 48 cores.
May not do much for Word files but when I am converting full HD video from MPEG2 to MPEG4, I could use all the help I can get.
On my last dual core computer some files took days. On my new quad core computer they take hours. I would love to fire up a project, get a cup of coffee and be done.
