My Athlon(tm) II X2 250 processor was released on Jun 2, 2009. It goes at 3 GHz. The 3 GB of memory comes from the same era. It is pretty much the only thing I ever do web stuff on. It is fast and I have no intention of replacing it any time soon.

What has happened is that maximum hardware performance has levelled off. Modern web design is slowly converging to a place where everyone needs maximum hardware performance everywhere.
