around 6 MH/s, Scrypt mining.
[some 7950 & 280x, pretty new, all of them]
Getting litecoins ~970khash/s with OC'd sli 780 and ~70khash/s with 4930k. Uses more than 1kW/h from a wall. Electric bill is included to rent.
btw, you might wanna consider NOT wasting your CPU clocks on scrypt mining ! 70 kh/s is nothin for LTC mining. try to mine some "CPU Only" alternative-coins out there, search them in this forum. [Protoshare, Datacoin, etc]
