CPU for a CF configuration w/ RAD 4850

[powerfuel]

Hi,
I was looking for an AMD 550BE w/ ASRock M3A790GXH/128M running on 1333MHz DDR3 and try to unlock a flawless core and O/C it to the max it/I can.

Cards:Radeon HD 4850 (x2 or crossfire configuration) it is turning around 100$ per card (225$ for x2 version)

I'll run on a resolution of 1920x1200 max setting w/ a 24'inch monitor. As I posted my build, I realised a crossfire configuration demands a good CPU. Can you tell me if this build AMD based can support these cards at their full capacity?
Thank,

If you're playing games that don't take advantage of more than two cores and you OC the crap out of it, you'll probably be good. I wouldn't count on unlocking cores.

You may want to pay a little more for an X3 720 BE and get a for-sure third core, but it will be clocked lower, but you can probably come close to the same OC if you're good.
