Link didn't work for me. Anyway, my favorite resource for hardware is "Tom's Hardware":
http://www.tomshardware.com/

I usually use Intel processors and Intel motherboards. Intel and AMD take turns at each being a little better than the other. Right now, Intel is ahead. I'm specifying my next PC as:
Intel Core 2 Duo e6600 CPU and Intel D6965WH motherboard. I'm planning to wait on Vista use and go with 64 bit XP Pro in the meantime (from my current 32 bit XP Pro)..

But i'm not saying that's for everyone - it's dependent on my needs, my budget and my (mostly) positive experience with Intel motherboards.

Just to let you know my level of expertise, one of the ways i make a living is as an independent PC consultant to individuals and very small businesses, so i specify and install and maintain systems constantly - about  30 systems at the moment. I've assembled my own for decades.

But i don't spend a lot of time tracking the latest hardware these days and i find that some friends who do, plus Tom's, the manufacturer's web sites and some industry journals provide what i need for spec info.
