Installed my new GTX 970 yesterday, hadn't opened up my PC for at least a year if not more and was so clogged up with dust it took me ages to clean it all out, amazing it was still running hehe
Anyways I took the liberty of running 3DMark (which I only got since it was super cheap in the winter sale) on my old GTX260 before putting in my new GTX970 and here is the compression

GTX 970:

Wasn't expecting that much of a jump and other than the GPUs its excatly the same hardware and setup between them, although with a load of dust removed
Cheers guys for all the help!
EDIT: BTW I'm a bit confused why my "GeForce Experience" can't optimize games?
I've got the latest drivers etc but it just doesn't want to work? Everything else looks to be working ok...
