What I have noted for some time now is that folks who put together DAWs professionally tend to use the Intel 865Perl motherboard and Intel P4 (whatever-ghz)e cpus. These are know for being rock solid. That is what I care about myself though I know there are faster configurations out there.
I've got Live 4 running on both an AMD 64/3200 (Asus mobo), as well as the above mentioned 865 PERL mobo with an Intel P4/3.4 (non-Prescott). The Intel arrangement is my main studio system, and it's absolutely ROCK SOLID. I run Sonar 3, Live 4, lots of plug-ins, and it all works great.
I have a Motu 2408 which is pretty picky about the chipset on the mobo; it doesn't like any sort of VIA chips. So, the Intel PERL has worked fine with it.
Beyond that, my main thought with AMD or Intel is that the Intel P4 (the Northwood, not Prescott...see this link:
http://www.theinquirer.net/?article=13847) runs very cool. So, I can use a Zalman fan at the lowest setting, and the box is nearly silent. Intel doesn't use a fan on the PERL northbridge chip either, so the overall effect is low heat, quiet, yet a very powerful setup. My experience with the AMD is that it runs hotter, needs the fan cranked up, and most of the mobo's that host the AMD 64 use a fan on the northbridge/southbridge chips. Result is a noiser machine.
Performance-wise, I'm hard pressed to see much difference between the AMD and Intel. YMMV, but music apps in my experience are at least equally tied into RAM amount and disk throughput. So, my Intel PERL setup, with 1G of RAM and SATA drives, runs at least as fast as the comparable AMD 64 setup. Both are nice systems, and about $700 each through tigerdirect.com and/or newegg.com for parts. (actually, the Intel PERL is the better deal, the hype on 64 bit has driven the AMD 64 prices higher and the Intel P4 prices lower. I saved about $150 on the PERL system over the AMD)
Last comment: 64 bit is a ways out for us in the consumer marketplace. I use 64 bit OS's at work (IBM) quite a bit, and for the "typical" music app, it's not going to make much difference even if it's 64 bit app. At least, not until there is a solid base with the OS (for most of us, that's a year or two off with either Microsoft or Apple), tied in with a solid 64-bit app (almost all music vendor apps are 32 bit still)...both of these coupled with your willingness to upgrade RAM, CPU, and mobo (in other words, a new system). To really take advantage of the next leap in platform performance, you'll be looking at the PCI-X bus, and again, not many peripherals there.
There's certainly a sunny future ahead, but IHMO, buying an AMD 64 with the thought that you'll be supporting your new 64 bit OS on that same mobo might be a little optimistic. I believe the AMD 64 is a nice 32 bit chip, but unless you want to run a 64 bit Linux on your current system with the AMD 64 chip (and Live doesn't run on Linux...yet), I'd look seriously at the Intel PERL/P4 combination for rock solid performance and cost savings.
And this comes from a die-hard AMD enthusiast!
