I recently build a new computer, and I've noticed that it's not performing as well as it should. I've got a laptop that's faster than this, which is what I was trying to replace (The graphics performance, at least, is a lot better on my new computer). When I start up my computer the computer is often slow, with the mouse freezing for a few seconds while Steam opens, and then again later when Skype opens. My laptop's fine with this and I get no lag during start-up, and that's only got half the cores and just over half the clock speed of my new computer. Also when running multiple tabs or windows it seems a bit slower than my laptop. I'd like to know if there's a way to improve my performance (I've already OC'd the CPU to 4.00GHz) or if I'm missing something or if my expectations are too high! Help is appreciated, thanks!
