I'm planning to get a 7800GS, which brand would you recommend? XFX and eVGA have their overclocked versions of this card. BFG I think has lower clocks. Also which one has more overclocking potential??? XFX is 440mhz core and 1300mhz memory and eVGA 7800GS CO is just 10mhz lower on the core. In eVGA's website I've seen a superclocked version, which costs much more of course, 460mhz core and 1350mhz memory.
