It can go based off of your temperature or tdp, how much voltage will also affect it. Also depending on the video card you get, say.. DC2, SC, Gaming, Windforce, whatever.. different bios will have different tweaks so they will all have different boost clocks. Of course you could have similarly/the same if you have the exact same model/bios loaded on to it.
Alternatively if you're on SLI or have multiple cards, one can be running hotter than the other and may cause some lowering.
If you look at the kepler bios editor you can see the tables it sets certain clocks for different voltages.
