Wow $60 for a 4830? Darn good deal. Of course, to help make them that cheap they didn't bother putting in the bridge connector so if you wanted to crossfire them you are SOL. You could try downloading the latest version of Catalyst or visiting Powercolors website to see if they have any hacked drivers for this, but that still may not work. I'd return the cards since they are not CrosfireX capable as advertised.
