Sandy bridge is much faster than Nehalem, Nehalem is faster than Phenom II, Phenom II is basically the faster version of what I have. Also, I've done some tests myself, and compared my results all over what is there of the CPU benchmark graph, and I came to the conclusion that my CPU is not better than a Sandy Bridge CPU at 1.4GHz lower clock. Almost definitely.
in a perfect world we would all be piles of sand with no ability to form coherent bodies of body
