980TI still going strong! I don't play anything too demanding anyway and Ive taken real good care of it so fingers crossed it'll keep going till I can afford a new rig!
I also have a 980TI. I think mine might be dying though, sometimes my PC shuts off and sometimes it doesn't start up. One particular time I got it started again by removing my GPU. I just want it to last another year but we'll see.
