So poking around GPUGrid forums I find this Memory Sucking Monsters and evidently no way to not get them if you choose long work units.....

So a dedicated GTX460 looks like on shorts it might get 60-80k a day and on longs, not Noelia's, would get about 140k a day, a dedicated cruncher. But NOELIA's need more than 1 gig GPU memory...

If these memory hogs effect the dekstop use I am gone again. And for the same reason.
