What FPS do you consider acceptable? 980ti 60FPS+ @1440p Tomb Raider.

Well at least 76 Hz or so (lower than that and it is a bit sore on the eyes). In the video there the 980ti fails to maintain 60 Hz........ it drops below which means that you then have sync issues (can be mitigated if you have a gsync monitor which I assuming the OP does not as he is buying a cheap GPU). For me to consider something running it properly it must maintain the screen frame rate constantly, no spikes or else it isn't actually handling it.....
