First home built pc...did i f-up

[meceve]

Ok this is my first time building a system myself....ok
my question is this:

Did i screw myself with this motherboard.....since its one of the first ASUS motherboards that support AMD2 processors?
I noticed that most of the newer boards specifically state things like dual L2 cache support?
Am I going to get any benifit out of my dual processor?
Any information one can give me will help?
Please give me as much help as possible I am a novice but understand the technology

All you have to worry about is whether it supports an AM2 chip, which it does..
