win2k or XP for better Xeon performance?

I am currently running a couple Dell PowerEdge 1750 with dual Xeon 2.8Ghz chips, Win2k server installed. I don't really need to run a server OS, and I do remember reading somewhere that when it comes to HyperThreading XP is better than Win2k.

I realize that 2.8Ghz is 2.8Ghz is 2.8Ghz is 2.8Ghz no matter how I look at it, but my question is whether I would gain any kind of performance boost in terms of multi-tasking by installing XP Pro? The machines run distributed computing clients, and not much else. Currently, when I start the client, it automagically spawns four instances and gets to work.

Thanks in advance for any suggestions you may be able to provide.
 
Thanks guys. Win2003 isn't an option. We have a site license for MS Products, but at some point they decided not to include Windows Server in it anymore. XP Pro it is.
 
Doesn't that give you 4 logical cpu's. I don' t think XP pro supports all 4, I read that on some other thread. You may want to get a copy of 2k3 enterprise... datacenter seems a bit excessive. Maybe the basic win2k3 may work.

Well, xp pro supports the pentium extreme edition and it is a dual core with hyperthreading that equals 4 logical cpu's.

I run xp pro on my dual xeon setup and it works fine

Actually, Windows XP Pro does support all four logical CPUs, in this instance. Windows XP Pro supports up to two physical CPU sockets (each of which may contain as many logical CPUs as that processor class supports), and simply needs the correct mobo chipset drivers in order to recognize all four logical CPUs.
 
So if you had 2 sockets with 2 duel core (extreme edition each with hyperthreading), it would work in xp pro, it would see 2x2x2=8?

More like two sockets with two dual core xeons that had HT enabled.

It appears XP Pro supports up to 32 logical CPU's. It's a matter of cramming all of those in the two sockets, heh.
