this is how the new 630 is ...
The new Athlon Quads are quite capable for their price. And Werxen is right, you should do a little research first.
You never stated what you intend to do with said system (gaming, encoding, web browsing, etc). And that would make
a difference in a recommendation.
I Assumed you were going to be gaming (my bad) and as such, figured the higher clock speed and L3 cache, along with the
known overclock potential of the 720 would do you better than the extra core.
