Yes, I'd be using it for FM and literally nothing else.
Just realised an alternative. I have this netbook:

I was given it as a teacher for OpenOffice and browsing. If I uninstall all non-important files/programmes, and install Steam (can store the files on an ext hard drive to relieve some burden), reckon that would be good enough?
Not bothered if it runs a touch slow, or about quality match graphics (I still admire the 3d engine in fm14 ffs).
