Most people are extremely CPU centric in their buying decisions, putting their money on expensive cpus just to run their browsers and family photos through picasa, a total waste of money imho and a sad state of the modern computer industry.
That's because the CPU is the single most important part of the computer. A computer with a shitty keyboard or slow hard drive will suck, but it will still work. Browsing the web on a computer with a slow CPU is impossible; it literally doesn't work. I tried to watch a blip.tv video on my Celeron 520 laptop a few weeks ago and it froze the browser. I restarted the computer and it took about 5 minutes before the CPU usage dropped below 80%. That computer can't play downloaded .flv videos and it can't play DVDs. All of this stuff is CPU-limited.
I typed this on a Phenom 9600 quad core. I have 5 Google Chrome tabs open with flash and everything and it's still super fast
