Goodness, I only got a graphics score of 18685 (although at stock, just got the card today). What overclock are you running?
If I remember correctly the run had +210/220 on the Core. I run the card @ 100% fan speed in 3D Mark when running the benchmarks to get as much as I can out of it. But it gives you a solid idea of what these are capable of if under water for example
With a more conservative Overclock +120/130 gaming I usually get around 2020/2040 core speed consistently which is really nice
