hi all, my first post in here. i am looking at two all in one sytems for my wife. one has the i5 4440 and the other has the i7 4770 but there is a big price difference, my question is this, is it worth going to the i7? the main use is e-mail via outlook with around 3, 000 emails in it (dont ask why) voice rec with dragon naturaly speaking and web design using artiststeer. no video work and no gaming. would i be better of getting the i5 and upping the ram from 8g to 16?
