Except the sorts of things that rely on the host PC for all/most of their processing (Winprinters/Winmodems), aren't limited by the host PC's CPU. If you've got a Winmodem, doubling the host PCs CPU speed doesn't double performance. If you've got a Winprinter that does 8 PPM, getting a faster host PC CPU doesn't mean that you'll start getting 10 PPM as printer performance is limited by how fast you can physically feed paper or how fast you can get the print head to traverse the page.

If a peripheral is taxing the host CPU enough that upgrading the CPU will increase the performance on that peripheral, it's already taking up too much of the host CPUs time.
