...I have not thought of the 256MB variants and 512MB are enough for any sensible amount of concurrent WUs, but it would be interesting to see what happens, just in case.



On my system the WUs "stalls" when more than 6 WU are run concurrently, ie the CPU and GPU usage goes to 0%. Restarting Boinc manager solves the problem for a while then it just stalls again.

Quick notes:

* ~20s GPU crunch times on i920@3.5 + 3850/256.
* You can feel the whole machine lagging when the GPU fires up lol. (think the problem is noted a few messages ago)
* ~450s CPU runtime? I hope there's a way of disabling the GPU part so I can run this on my other x64 box with Nvidia card...
