Multiple WU's per GPU
Vyper:
I have a done a quite thorough benchmark over at my blog containing performance data of various official/unofficial executables and benefits when doing full WU runs.
Head over there to check..

Kind regards Vyper

They just won't benefit from doing so directly, since context switch hardware wasn't included until Fermi. Since you have 400 series there, the likely benefit will outweigh any added cost penalty to the older card (Your mileage may vary).
Note that the operation you're seeing is AFTER, many driver revisions & improvements, so I am surprised that it is working also. Joe's statements were quite correct not so long ago (though I can't pinpoint the exact dates/versions of the corrections . Too many changes too quickly ;))
... Cuda 3.1 was most definitely broken with mixing generations in the same host, which I reported through nVidia's registered developer program. These things are fixed in Cuda 3.2. The Cuda 3.0 build in operation, should also be fine as your host shows, just be certain to keep an eye on things ;)

So, err, just so I have it spelled out to me: ;)
My 8800GTX should also be able to run 2 WU's at the same time, but it will not make any difference in the total throughput?
So, bottom-line, the current way it crunches (1 WU at a time) is fine and dandy?
Regards,
Patrick.

the key is that newer GPU's can handle the multiple apps running. older cards cannot
