I think there was an article last week or so. On the Athlon II line though, the x4 looks awfully tempting to me to grab one and overclock to have a budget gaming monster.
A good board that has a little bit of everything (since Im not sure on what you are using this computer for) is the ASUS M4A785TD-V EVO. AM3, DDR3, and 2 PCIe slots.
I don't know man, if you are going to overclock anyway, I'm not sure I see going with a cheap triple when you can get a quad for 10-20 more, just my 2 cents.
