Update your driver to 14.6 for better hashrate
There's 3 .bin file for 270x, 280x and 7950 in the archive for anyone don't have driver 14.6, and remember set --gpu-platform 0 for 13.12 driver
Currently performance :
7950 : 3.6MH/s (1030/1250)
270x : 2.85MH/s (1100/1400)
280x : 4.5MH/s (1100/1500)

Don't expect any further optimization because those algo was optimized already
