I've normalised all the results to my old Q6700 workstation assembled in Autumn 2007. As you can see, the 3770K is around 2.5x to 3x faster on paper (AES encryption is bananas faster, some 13x times thanks to new AES encryption hardware assist in newer Intel processors).
Yet, as clock speeds have only improved by about 50% in the past five years, while I'll notice the new workstation is somewhat faster, I won't really feel the difference. Nor would I for probably another five years ;), so let's hope this upgrade maintains the distance till then.
I won't be replacing my old workstation with new until I get a LGA1155 mounting kit for my new uber CPU cooler, a Noctua NH-D14. Yes, it really is that massive, and yes it does have two 14cm fans. I'm not even sure it's going to fit into my Antec Solo super quiet case actually. Fun!
