I get better hash results in linux/debian (bamt) than I do with windows, probably because my hardware (ASRock 970-EX4 w/ everything disabled but USB and GPU) is 100% what BAMT was built for, so all the built-in drivers are prepped for the hardware.
Using other hardware, it'll be mixed. And when building linux from the ground up, unless you're good at building the drivers (sometimes having to use an old driver, which might take days to figure out) from scratch, it could lead to pulling your hair out.
That's another thing--I disable literally everything on the motherboard (via BIOS), except for the USB ports and built-in ethernet port. This prevents anything unused from taking power, and prevents any "unnecessary" driver issues. SSD is disabled, IDE, Floppy, Serial ports, IR ports, the whole 9 yards.. it's all disabled.
And I'm getting that particular motherboard soon. And I looked up all your old posts about the Toxic cards, and I'll basically do the same thing, hoping to get 805+ kh/s. BTW, Mark does not have the Toxics, he has the Vapor-Xs.
Also, in case you want to check it out, there are forks of cgminer, like sgminer and there is a custom build too. sgminer is Version 4.0.0 - 15th January 2014

I tried BAMT 1.3 on my testbench with a 280x toxic and a 280x dual-x, both give ~10kH more than in their previous setup...
