What's the main difference between these 2 boards. I'm building a comp. for someone that is just going to use basic programs like IE and MS Office (that's probably all that she uses.. she's a secretary at a church), anyway.. I bought here the Asus p4p800 delux, b/c I had the P4P800 in my comp, and have been happy w/ it. BUT She could care less if she had a delux or not, so if it's worth it I might switch out the mobos.. Anyone know if it's worth it? That'd be kinda a lot of work
