So I'm ok temporarily using the 730. My old card was a 670 SC+ which was insanely fast for 2012. The 8 series was mobile only, which means if I can't use the 9 series I can always drop back to the 7 series. This is complicated, however, because I know I can use SOME 9 series cards, the 950 for example was ok but not any faster than a good 7 series or even the 670.
I could easily sell this 970 SSC I'm using now and pick up a 780Ti and not lose any money on the transaction. Or I could suck it up, drop all the way back to the 670 (re-purchase it from whence I sold it), and call it a day.
It's frustrating because I simply assumed all nVidia cards were not terrible. But this is my first foray into 9x0, and it's not been pretty.
