The GTX 680 DirectCU II TOP features a metal backplate covering the entire back of the circuit board to almost completely nullify any possible flex. The board, itself, uses a process for higher strength with less flexibility, as well as a dual bracing system to reinforce even further around the GPU area and VRM, which is most critical. Reducing these microfractures prevents loss in conductivity along the circuit board, preserving optimum performance and preventing added heat build up (just like a light bulb, more resistance=more heat). A 10 phase PWM DIGI+ VRM with Super Alloy Power and Japanese made caps assures consistent, clean, precise power to the GPU. For hardcore gamers and tweakers, the GTX 680 DirectCU II TOP offers VGA hotwire allowing the board to be hardwired to select ROG motherboards for complete control directly from the BIOS. For the average user, the included GPU Tweak software provides excellent OC flexibility and monitoring to tweak the GTX 680 DirectCU II TOP to your specific needs.
