frame

I am working on a project to monitor if human tissue has been fused with radio frequency during the surgery or not, therefore we are using a very fast camera (1800fps) and also laser illumination on the tissue and a framegrabber (1GB memory).

I notice that, instead of a framegrabber, I'm able to use GPU as well, but I am not sure on what's the difference between them?

Can any body explain what is the difference between a frame grabber and a GPU?
