She lives in the same town. She doesn't use photoshop but does do video renering/conversion. But she has one of those Miglia USB video H264 dongles that is suppossed to take most of the pressure off the CPU's for that job. Other than that it's just internet. email and youtube. So I'm not sure she is getting any benefit from the dual processor setup she has. Thoughts?
