read the 680 lighting review. Wonderful review, with the overclocking features and voltages enabled, this card should fly. Im just wondering, for the card to reach 1300-1400 core clocks, its definitely possible but would you think it will be necessary to have the gpu reactor onboard? most likely so i would believe. running 2 lightnings in SLI would be perfect, but if any one wanna go 3 way SLI or even 4 WAy sli, the gpu reactor and its pcb will definitely hit the other cards.. i run the 670 4gb evga sc in 4 way sli driving 3 27" screens at 7680x1440 and i know what the gaps are like between cards. from the pics, even the lightning's backplate seems further from the pcb compared to the evga 760 backplate-pcb gap. the only way I can see this happen is with custom full waterblocks for the MSI lightning, which I doubt may be made unless the cards sales are really humongous. lets hope they release the full waterblocks soonest , before the gk110 is released..
