XFX 650 or SeaSonic X Series 650 Gold?

I would go for the Seasonic over the XFX any time. With just one 7970 I think the 650w Seasonic would be just fine. Truth is I really do not know alot about XFX but from what I have seen and read around the net Seasonic PSU's are better than XFX and I have owned a few Seasonic PSU over the years and they have been very good. The way I see it the PSU is one component you do not what to take a chance on get one that will work well and last even if it cost a little more.
