I have a Gigabyte AMD radeon hd 6670 graphics card and I'm about to get another one so I can crossfire it with ATI crossfirex. But it has no port to plug in a crossfirex bridge. So I'd like to know if it needs a crossfirex bridge. Also it did say on it's own webpage, that it is ATI crossfirex enabled. So don't say it's not please.
