Feedback from Ubuntu 12.04_amd64 with Catalyst 12.4 /HD6950@6870:
Boinc: last SVN version.

Runs fine, no computation errors if all dependencies are installed. (32bit libraries)

2 Tasks on one GPU give me 90-94% GPU-utilisation with CPU load of 12-14% (Core i7 4.3GHz) per Workunit.

Performance is (compared to nvidia) 1/2 of a GTX 470.

Today, AMD released a new beta driver, Catalyst 12.2. With this driver, Workunits are using 81% of the GPU (HD 6950@6970 full Shader). It could be even more, because the CPU limits the GPU-load. My Core i7-2600k ( 4.3GHz, only one Albert@home WU is running) is not able to deliver enough performance to bring GPU-load to 100%.
If the CPU starts crunching other WUs (one core is exclusivly for Albert@home GPU-Workunit), the GPU-load drops to 75% and lower.

Is there a chance, that CPU-load for GPU-WUs could be lowered in the future?
