I need some place to start when considering a used laptop purchase. My understanding that having a windows or linux OS w/ an AMD or NVIDIA gpu really helps w/ number crunching on NumberFields@home and otherBOINC related projects.

It's not a priority in the purchase but it is a consideration. For example, I don't want one so old that OpenCL can't run on it.

Is there a intro guide to this subject? Something along the lines of "GPUs and BOINC projects for Dummies". Maybe a place where I could compare different GPUs commonly found on laptops and their number crunching abilities

I was hoping someone else would chime in, since I don't have a good answer for you. All I can say is the NumberFields app runs best with a 1000 series or better Nvidia GPU or equivalent AMD GPU (but Nvidia is slightly better since it utilizes CUDA instead of OpenCL).

believe it or not, just that info alone is helpful for me.
