I have two of each of the GPUS. Sadly... all around my 8.8 MH/s gets me only 10 DRK/day in this new difficulty and I wasn't around in the early, early days. Profitability's crap, but I'm too lazy to mine and dump something else and I like the temperatures.
I added both GPUs and your CPU to the list. Thank you!

Can make both go much higher, but I like rock solid stability over pure speed.
Can you share you entire command line for the 290X? My 290Xs or the 290s do not get anywhere near that hash rate. They are even below the 280Xs I have and I can't seem to be able to dial the correct setting.
I played with a setting a bit, it didn't change the hash rate.
290x = d 0
270x = d 1

I use sapphire trixx to overclock.
