It's a very interesting design. No need for the single or double card selector paddle like all the other brands. Instead, they just have 3 PCI-E slots, the middle one being the single card slot and the outer two being the SLI enabled slots. This design actually has been shown to improve overclockability because there isn't anything to limit the overclockability like paddles or jumpers.
It overclocks pretty well...within the league of the DFI LanParty series motherboards which are notorious for their overclockability. Jetway has done a great job with this motherboard and the very creative and effective SLI layout. This board really deserves the attention that it should get.
