The GX650 was summarized by HardOCP as a "polished turd in a box." Treat it like a 550W PSU, and you'll probably still be okay. That's enough for a HD7950, but if you planned on adding another one, replace the PSU first.
To your specific question though, I'd probably choose an Asus board, especially if you plan on a relatively high OC. If your OC will be none-mild, ASRock would be good too, or one of the better MSI boards (I don't trust their cheap ones for OC).
thank you, im planing on mild OC , but to be sure ill go with an Asus board.
