I disagree with this comment. I have a Biostar A780L3G that can handle a Phenom II x6 1090T and 970. I test it myself and also add VRM coolers and NB fan on it.
This mobo is not oc friendly, but it can run any AMD AM3 cpu at stock without a problem. It has a 4 phase power on this mobo.
Edit: to be safer, you can always undervolt the stock vid which is usually higher than needed anyways.
