Use for a dual cpu motherboard

[kjbits]

I have an ASUS CUR-DLS dual socket 370 motherboard which I think came out of a sever at some point.
I already have a 1G processsor and thinking about getting another to fit it but I need to know what use can I put it to. Will it run a standard version of XP? or do I need a server version?
If so is there any advantage to having 2 processors? like do they share tasks between them? if I was running 2 or more programmes at once.

nearly all of them needed registered memory

Hope some of that helps.

Thanks for the replies, might be a bit thick here but what is registered memory?

Right ok.
