NVIDIA will now allow you to overclock the display screen by making custom profiles, so you can check if the monitor can take like 70 or 80 hz (or whatever). If you have found a compatible refresh rate you can apply it and keep using it. So you break away from the 60Hz limitation.
They go from allowing overvoltage on the cards, to even OC'ing our monitors now. Nvidia's back in the OCing game finally. Wonder if any of the partners will take out the option to overvolt. I doubt it, if they want to stay competitive.
