Well you do know in advance that nVidia doesn't work on linux.
With relatively new distros (kernel less than a year old), there will always be problems like screen tearing, stuttering, crashing, etc... with the proprietary nVidia drivers, that is IF the driver modules even compile in the kernel.
If you want a decent experience with nVidia cards, stick with Debian stable, maximum kernel 3.8, proprietary drivers, and don't ask too much.
If I had a GTX780, to be perfectly honest, I'd be using Windows, that's what it's for.
Don't expect good nouveau drivers within the first couple of years. nVidia will fight open source as long as it can.
