Alls I know is it's a heckofalot faster than my hubby's Toshiba laptop. His computer was new in June and that thing, while fast to him compared to his old HP, is like watching a pot of water boil!
So a few more secs here & there doesn't bug me too much. I'm glad I got what I got(a 3).
I have a feeling that you really get to point of splitting hairs with speed.
