Can a GTX 780 Ti handle the shadows?

For what it's worth, I can have cloud shadows enabled and ground shadows turned off and I get pretty good performance. I have a GTX550 Ti.

To me the cloud shadows add more depth than building/vegetation shadows, though I would like to be able to run both. Usually I'm flying GA, though I had a little fun with the F22 around Ithaca, NY and let me tell you that punching through a 3500' scattered layer and looking back and seeing all the cloud shadows... well, the tradeoff for me is worth it, but others may prefer building shadows on all the time.
