Are these hashrates with your sgminer in your signature?
yes it is telling the server my hasrates so it can decide what algo's are profitable for me
I'm getting significantly lower hashrates on my 290x than you are, so I'm going to try the sgminer in your signature with the settings in your codebox. Are you on Windows? I'm Win 7 x64 with 14.4 drivers.

He has gpu-map which may not apply to you, and these two things
"gpu-engine": "750-1000",
"gpu-memdiff" : "300",
