Minimum CPU requirements for decent FPS



I use an ASUS UX31A-R4048H with an Intel Core i7 3517U 1,9 GHz CPU. This gives me a framerate of around 30 which is really great.

However, I´d like to get a dedicated computer for my OpenROV. A Chromebook would be fine but the ones I've looked at have fairly weak Celeron CPU:s, at least compared to my Asus.

Has anyone tried Chromebooks and which framerates have you got?
