single or duel cpu mobo

I'm looking into building my own server and I'm in pickle I
don't know if I should go with a single cpu or a duel cpu I have been looking at the Gigabyte

put a P4 2.8ghz cpu NW

I also looked at MSI and ASUS But I don't have a lot of money to spend If I could build it and keep my costs under $1000.00
(and then I woke up) lol. I'm looking for opinos on my choices and any other choices for a server mobo


Thanks for you time

I will kinda depend on what you're using the server for whether you go with a dually or not. If you have cpu hungry apps that are multithreaded then dual CPU's is a no brainer. If CPU power is unimportant, then get a single.
