CLEVO P370SM, 680m to 980m

[Acarbonbasedlifeform]

Hello,
As I mentioned in the title, I own a Clevo P370SM wit GTX 680M in SLI.
I am considering an upgrade to 980m SLI next year.
However I cannot find info anywhere whether this is possible or not except some people mentioning about BIOS update which I am not really good at.

Can I get this upgrade done in a computer repair shop?

Thanks a lot for feedback

I'd assume your local computer electronics store could do it. However, it's not that hard. Especially if you update it inside windows.

I see, so there is no hardware incompatibility preventing an upgrade from 680m to 980m, is that right?
Also, to my knowledge GPUs don't really change sockets does that man I can also upgrade to the successor of 980m assuming the heat output is acceptable?

And what is the difference between P370SM and P370SM-A?
