@Radiance :I have noticed that the lines below are still present in the GPU-X link on top of Octane site. As the comment mentions a solution at the end of 2010, and as there is no hardware solution provided by RS, maybe removing these outdated lines would be suitable.
Therefore we are currently researching another very promising option which will offer a cheaper, smaller and more flexible hardware solution for our users needs.
We will announce our new hardware compute add-on product at the end of 2010.
