Can someone write me how and what files to configure for multiple gpu configuration off cgiminer.
I have one computer with 4xr9280x and one with 3x5870, and 1x5970.
I am now mining with gui miner scrypt but have problem with ati display driver it breaks. Or give me a very little KH about 400kh for r9280x-oc gigabyte.

Thank's in advance.
