Used to be a huge AMD fan, then Intel's Core 2 processors started showing significant gains over the 64 X2 processors AMD had, and now that the market is starting to semi-stabilize for now, I have to say I still prefer AMD. While I was a bit mad at AMD for changing from 939 architecture to AM2, it made sense, and as long as they stick with it for a while, my AM2 motherboard when I get it should hold up for a while. Intel, meanwhile, has been using the same LGA775 architecture, which while lending itself to upgradability, most MoBo's had to be replaced anyway when DDR2 came out, as they will when DDR3 prices come down enough to make it affordable for the mass market. Also, while same-speed Core 2 processors will generally out-perform their AMD counterparts, the AMD processors are much less expensive. If you absolutely have to have cutting edge performance, go Intel; if you can stand being "just" cutting-edge, AMD will more than suffice and for less money. I also tend to find AMD MUCH more overclocking friendly; never had a problem OCing most of my chips 20% over spec. My x2 3800+ has been running stable that way since I got it (2-3 years ago). Anyway, just my $0.02.
