You can check the performance of the card in the Agisoft  console.  Its reported there once the dense cloud has finished processing.  The recommnedation is to diable 1 core per GPU.  So in your case disable 1 core.  By default one core should already be disabled.  For fast cards such as 980 and Titans the recomendation is to disable all cores as the GPU is faster than the CPU, at least that is how i have understod it. 

No idea what performance your card has.  980 is around 900 milion samples per sec i have herd so a bit less than that.  Test it and report back.   You can also disable  all cores and test the  same data set again and see if you get an iprovement.

Also, which numbers should I be looking at? Testing now.  I already noticed that Photoscan was using the Intel4600, instead of the 970m.  Changed that in the NVIDIA control panel, and it's running off the 970m now.  I've disabled 2 cores, and am testing with 52 cameras, that are geo-referenced. Testing a high accuracy dense cloud.  I'll disable only 1 core next, and see what the difference is.

[UPDATE]  With 2 cores disabled it completes the task in 1991.04 seconds.  With 1 core disabled it completes the task in 1837.46 seconds.

I only want to do smaller processing on the laptop, so maybe I'll just spring for the max of 32GB. Around 20Acres at a time, at as high a quality as possible. 

I'll be needing to map larger areas this North American summer, and I'm starting to look at workstations or network processing.  My department has 3 lab areas with networked computers ranging from Core 2 Duo's with 2-4 GB ram, to i7's with 4-8GB ram.  It's a bit of a mish-mash, but we have around 30 of them.  Would it be better to use the network processing feature on photoscan (How does licensing work then?), or to spend 3000-5000 USD on a workstation?  The university gets pretty good deals from Dell.

Will do!

My laptop also has a build in Intel HD 4600 gpu.  Should I enable this as well?

Interesting stuff! I have a few questions:

What sort of performance could I expect from an Nvidia 970m with 6GB DDR5 Ram?

How can I test that photoscan is using the GPU?

How many CPU cores should I disable for this card? Just 1?

Should I use the Intel 4600 gpu, built into my i7?  As far as I know, it uses system RAM.

Thank-you!

I want to use Photoscan for orthophoto and mapping purposes.  My laptop currently only has 8GB ram (4GBx2).  To speed things up, should I get another 4GBx2, or 8GBx2?
