Thanks Stash, it seems a good time to put this dinosaur OS to rest. It served well.
Most likely I will go with XP pro. Although XP is a dinosaur of its own I am not too fond of the things I hear on Vista.

Yes, Windows 2000 does support multiple cores.
It even supports Hyperthreading. I've ran a P4 w/HT on Windows 2000 Pro without a problem. Windows 2000 will also see all cores on a CPU as well.

It can see them but it can't distinguish between physical sockets and logical cores so Win2K Pro only supports up to 2 cores and won't manage the shared resources as well as XP and up.
Yes, but we're talking about a quad core here. 2000 Pro only supports two CPUs, and the OS can't distinguish between a core and a socket. If you have a single quad core CPU, Windows 2000 will only use two cores. XP or Vista will use all four.The license support is per processor socket. If there's multiple cores on a single socket then it will support it.

Or if you had two quad core CPUs, 2000 Pro will still only use 2 cores, whereas XP Pro and certain versions of Vista would use all 8 cores.
No kidding. But again, 2000 cannot distinguish between a core and a socket. Which is why if you drop a quad core into a single socket on 2000, it will only see 2 cores.No, it only supports two processor sockets per the license. That's what the OS distinguishes between.
No shit. That's what I just said. It's what I posted with the link in my first reponse XP Home supports a single socket with unlimited cores. XP Pro supports two sockets with unlimited cores. The different versions of Vista are the same.Why do you think Windows XP Home will support a quad core? It only supports a single CPU socket but will support a quad core processor. Heck, if a 6 or 8 core CPU comes out it will work on Windows XP Home.

What are multichip modules? Does the multicore and hyperthreaded processor licensing policy affect licensing for multichip modules?
Multichip modules are multiple, separate processors aggregated into one package or board. The multicore licensing policy does not affect licensing for multichip modules. For server applications licensed per-processor, a separate license is still required for every processor in a multichip module.

According to that - MS isn't even following their own licensing guidelines, when dealing with Intel processors!

Both the Pentium D dual-core, as well as the Q6600 quad-cores, are multichip modules, two seperate CPU dies in one package.
According to MS's guidelines, those chips should take up the equivalent of a dual-socket license.
Apparently, MS is breaking their own guidelines, in order to convey favor on Intel. If these guidelines were properly followed, then AMD's native quad-core CPUs would have a software licensing advantage over Intel's. But of course, MS supports Intel's monopolistic efforts over AMD.
iirc all the Windows 2000 product stickers are labeled 1-2 Core.
