I just went through a chipset review and decided to go with the SIS 645DX chipset and Intel P4. I have been using a PIII 600Mhz overclocked to 811MGHz.
Let me backup up first to tell you how I got there.
I went with Intel mainly because I use Sonar and there were some blurbs on the net from one of the programmers at Cakewalk that they acutally have Intel specific code in the software. Also, I have both processors here at home and frankly, I never have problems with the Intels and although I have solved the AMD issues, they tended to involve more tweaking before they ran smoothly. They have not been bad but just too time intensive.
I wanted a P4 in the 2.0+ range and, looking at prices, decided on a 2.26 with 533FSB, 512cache. The SIS chipsets are getting rave reviews for speed and performance over at
www.tomshardware.com . This is above similar Intel chipsets 845i etc. The 645DX was less money with higher performance ratings so I went with this one. Currently there is a SIS 648 chipset that just became available and so you might want to look at one of these. Asus or Soyo Motherboards are available with these on them.
Another cool thing about these SIS chipsets is that you can run DDR 2700 memory which when all is said and done screams at Rambus memory speeds without the compatability and stability issues.
Result: 50 tracks with plug ins no hiccups in Sonar. Life is good.
Unexpected suprise: For some reason my sound cards sound better running at the higher bus speeds the P4 allows. First thing I noticed. Don't know why because digital is 1s and 0s but things are audibly better.
Hope you find this useful.
