So I have a few Radeon cards laying around and I thought I would see what they can push as far as mining.  Unfortunately my main gaming rig is all Nvidia powered and I didn't realize the huge difference between the two companies as far as sha256 hashing.

Anyhow with that said I tried out xubuntu from a guide I found on the net, its a bit more complex to set up but was able to get it running but for some reason I was only seeing around 250, and well while the overclock tools or the various drivers I had to track down and try didnt seem to help.  I booted up the same box with a vanilla windows 7 with sp1, installed the proper recommended ati sdk 2.1 and c 11.12 drivers.  I also downloaded amd clocking tool and bumped up my core to 980 with memory at 300, no voltage change and boom I was mining at around 450 average for the same card.

Here is an included screenshot of the details.

Nice! I'm using the 13.1 drivers and 2.6 or 2.8 SDK and I'm only getting ~ 430 on my 5870 OCed to 950.

Everything I read *claims* that 2.1 and 11.xx drivers 11.12 recommended is much better.  They claim from what I have gathered that its a 10% decrease when going to up versions of the sdk.. not sure about the c drivers tho..

I get ~ 400 with my 5870 at stock speeds, using 13.1 and the default OpenCL sdk version.
