I was going to go with AMD, but in researching this entire mess, it was driving me insane. This is the kinda stuff I would see...
"Via had there issues fixed with the KT266a"..."Via still has issues up to the KT333" "The SIS745 is good"..."No the SIS745 will not work good with XYZ card"....
On and on and on. What I learned from all this is, that you can by an AMD and Via chipset or SIS or AMD 76x and it could work well for you. Hopefully it does. Or it could work ok and you would be spending a lot of time tweaking and hunting message boards for help, or you will be completely screwed and will buy and return and buy and return components until you get it right. The problem is not with AMD, it is with the MoBo chipsets. I have not read any consistent, solid performance. I want to record music. I don't want to worry about tweaking until the cows come home. I wanted to go with AMD, I really did. But in the end, I chose to go the Intel route. I was looking at a AMD 2000 XP, but decided on a P4 1.8 Northwood. It was only like $70 more.
On another forum, one of the members came across a solid Intel setup for DAW that other members have also used, and from what I read, it has worked flawlessly for most of those people.
Is Intel guaranteed to work 100% of the time...No, but it is like a 98% thing, where as AMD seems 50/50.
