Hi guys I am upgrading my PC, I will be getting Intel I5-4670K CPU /W Noctua NH-D14 Cooler, Corsair TX850 PSU, 2133 Corsair Vengeance 8GB Ram kit, MSI Z87 MPOWER Mobo, And when it comes out, MSI GeForce GTX 780 Lightning ED, But I'm a little confused about the "Unlocked Voltage" of the GTX 780 Lightning as shown here http://event.msi.com/vga/lightning/gtx770.html#OC (Yes i know that it's the GTX 770 but i assume the GTX 780 Lightning ED would have the same features.) I do of-course plan to overclock my GPU, but with the unlocked voltage will it be safe to do so? I know that low to mid-end overclocks will be. But i'm looking to push a high-end overclock, i am just unsure as to if i will damage my GPU. If any one could explain this "Unlocked Voltage" to me it would be greatly appreciated.

It means you can adjust the voltage, so you can reach higher overclocks. You'll only wreck the card if you let it get to extremely high temps or set an extremely high voltage, but if you know what you're doing and taking small steps it will do no harm.

Sorry let me explain, how i currently overclock my GPUs is increase the core clock, when it becomes unstable i turn up the voltage a little bit, test for stability, then increase core clock some more, if its unstable increase the voltage yet again, how long can i keep doing this before i risk damaging my GPU? because it seems like the voltage doesn't have a cap.. or for this particular card do i only have to worry about temperatures so long as i increase the voltage in increments?

Well when you're overclocking you should always keep a look on the temps. Also what you're describing is an unlocked voltage. A locked voltage would mean that you cannot adjust the voltage so if your overclock becomes unstable you need to downclock instead of adding voltage.
