Very happy with this processor. However, I was upgrading from a 2nd generation i5 and was surprised that this wasn't dramatically faster than my old system. I do a lot of video editing and rendering and was expecting a noticeable improvement in rendering times, however while it is definitely faster, it's not greatly so. Having since seen reviews of the AMD equivalent processors I suspect these might have been more suitable and faster since they offer multithreading which the i5 doesn't.
Other than that, I'm very happy with my new system built around this processor. So far it's proved rock solid, responsive and reliable. Recommended.
