Testing if main core ( gpu clock or shader clock ) is bottleneck is easy.
Its called "gpu load" and there are lots of programs which show that,for example msi afterburner or evga precision can even show it in game while you are playing.
If load is at 99% it means gpu is bottlenecking ( it never shows 100% for some reason ).
Testing memory bandwith is a problem,because I havent found any program which can show that. MSI or EVGA can show memory usage,but thats different.
I guess only way to test if memory bandiwth is bottleneck is the way NV suggested : try to overclock it and see if perfomance improves
