I found myself wondering what is going on with gpugrid because i get more and more units who take more calculations on the cpu.

Hi, looks to me you 'upgraded' BOINC from a 6.4 to a 6.6 version. I had this happen and with me it was because of a bug in BOINC. If you go back to 6.4.x it will be twice as fast again.

I correct myself, you are using 6.5.0. I notice that the estimated time beloweach successful workunit is more or less the same at 88000. It is the CPU score that varies strongly. It may be that the involvement of the CPU varies strongly based on results, but does the result itself take significantly longer on a real clock ?

Yeah, it's just you ;)
but what is worse is they get rewarded much less even though they take much more power.
Let's do the number for my rather typical WU 1 and WU 2 with low and high cpu usage, respectively.
WU 1: 45297s -> 1.90 WUs/day -> 9628 credits/day for the GPU. The CPU would yield ~4000 credits/day without GPU-Grid. GPU-Grid needs 1.9 * 1775s of these, that's 0.94h or a reduction of cpu production by 39 credits to 3960. Sum: 13588 credits/day.
WU2: 41744s -> 2.07 WUs/day -> 9856 credits/day. CPU: 2.07 * 5928s -> 3.4h -> a reduction of cpu production by 142 credits/day to 3856. Sum: 13714 credits/day.
So in this case the WU with higher cpu utilization actually earns more. The precise numbers will vary from system to system and from WU to WU, but I think this should be proof enough.
