It's like we all have this hardon for cpu numbers, and its a habit formed years ago when it really mattered a lot more - back in the days when cpu's were 300mhz, then 500mhz, etc. Nowadays cpu speeds far far exceed most peoples needs. And more important is gpu numbers and hard drive numbers. But old habits are hard to break and we still look at cpu numbers and get a hardon.
I recall how excited I was when I purchased a 90MHz Pentium PC to replace a 16MHz 386 (which I was equally excited with when it replaced an 8MHz 286).
The 90MHz Pentium was replaced with an 800MHz Athlon, then a 1.3GHz Pentium M (which ran Windows XP as fast as a 2.0GHz P4). Since I switched to Mac, I've had a 1.8GHz C2D, a 1.86GHz C2D, and now am getting a 2.13GHz C2D. The pace of CPU speed increase has definitely slowed down now that we are more interested in CPU cores, GPU, RAM, etc.
