You monitor your temps? How high are they when you see the speed drop? Likely what's happening is thermal throttling. liquid cooling will definitely help there. Blocks for the 10 series have started popping up too.
In the overclocking utility there will be a monitoring section what your looking for is "Voltage Limit", "Power Limit" and "Voltage Limit"
The voltage limit is the flag that the drivers report when you hit the voltage limit on the card, it is either a 1 or a 0 meaning yes or no
The power limit is the flag that the drivers report when you hit the set power limit of the card, it is either a 1 or a 0 meaning yes or no
The OV limit is the over voltage limit, this should always be 0 as it is when you unlock the standard max voltage to the GPU and go over it which means you are frying your card.
If all these values are 0 and your card is not increasing in speed, you are thermal throttling.
Getting 2Ghz on the 10 series is not all that hard. 10-25% OC.
I have gotten 43% OC on the GT710
An easy way to get more clock speed is going into the overclocking utility and setting a more aggressive fan curve.
nvidia want a silent high end card so the fans on the founders wont go over 50%, but you can set the fan curve higher.
Just by making a more aggressive fan curve you can get a higher overclock since the card is running cooler which means GPU boost can keep increasing the clock speed till it hits the Power Limit or it gets too hot.
After some testing in Unigine Heaven, I think I'm hitting the power limit. I can only go as high as 112%, and my card has an 8-pin. Guess I should have gotten an 8+8 pin GPU with more power phases. But it's not thermal throttling, as the highest I've seen is 73 c.
I could set an aggressive fan curve, but the card gets pretty noisy. Can't really focus when it's that noisy..
