I still have a Pentium 4 computer I built over five years ago. It’s a little sluggish, but since I never pay the premium for top-of-the-line CPUs I figured maybe I could grab a cheap upgrade — after all, Socket 478 processors became obsolete at least four years ago.
Apparently that’s not how things work: High-end Socket 478 processors are still going for hundreds of dollars. These are processors that are slower, more power-hungry, and less capable than the cheapest Intel processors currently manufactured (which are selling for under $50). For the price of one of these old processors one could buy an entire new, faster computer!
