The link for the AMD CPU went back to the mobo for me
If you decide to go the pentium route, the mobo and CPU you listed are NOT compatible. The mobo is socket 478 and the CPU is 775. Also, that CPU is only 533fsb. I would go with the two below. This will be a big jump over what you listed for minimal cost increase and is socket 775, meaning you could go 64-bit if you ever desire and has the 800fsb.
