My workstation was recently "upgraded" from a Window 8.1 workstation with a 4th gen i5 to a Windows 10 laptop with 5th gen i7. The extra RAM and SSD over HDD is great, but whether it's because it went from a quad-core to a dual-core hyperthreaded CPU, or because of the jump to Windows 10, the mouse lag is considerably more noticeable now. I've convinced them to upgrade my laptop again, but now this article doesn't give me much hope for my new work toy.
