How to control a R9 280X power?

[gontho]

I am going to a old 1024*768 monitor because the one I had broke. I believe its 60 or 75hz, so my actual CPU and GPU are overkill, so I would like to maintain the system the coldest and the quietest. If i dont need more than 100fps fo example, how can I config my GPU to not process more than x fps? I know there are command lines, and have though of Vsync as an option, but dont know really how it works, because in my last monitor I had not experienced any kind of stutter, so never used it.

Thanks, and hope you can help me

Afaik you can't, you can only really tell it how hard to work. E.G 50% power.

you can't do it by fps but you can under clock it to reduce its power and heat

So that means undervolting?
