Hey Everybody,
     I'm going to build a new office PC. I would like some advice. The biggest question I have is, what operating system is best suited to this machine?  If I use Microsoft Windows XP Professional x64 OEM will I be able to use this with Mach and the rest of my programs? I don't have the drivers for Mach installed on my office PC. I only use it for test and tune in the office and that is limited without the drivers. Here are a few links to the components I would like a thumbs up or down on.

Thanks for any advice,

Unless you're running 64bit versions of your software, there's no need to use a 64bit OS, IMO. The best processor right now is an Intel Core2 Duo. Blows away Athlon X2's for speed, and runs a lot cooler at the same time. I have an X2 4400, and I like it, but if buying now I'd get the Core2 Duo. They weren't out when I built my current machine. I'd go with XP Pro, btw.

Thanks Ger,
    I will go with XP 32 OS and look at the pentium processors.

Thanks again,
Brett

Hey Ger,

Is that the most expensive motherboard made. 

Unless you need every feature on that board, I'd go with a good mid range board, $150 or so, maybe a bit more. You'll save enough to get 2 gigs of RAM.  Read the reviews at Newegg on the different boards. You can't believe them all, but they give a good idea if the boards are any good. I got an MSI for my X2, and have been very happy with it. fwiw.

Yes, it is pricey. Thanks Gerry.
