What GPU are you rocking?

GTX Titan X at the moment. Bought it on eBay for pretty cheap and it was in bad shape. A couple of firmware updates and pulling apart/cleaning/wiring in the fan and its rolling along nicely. I have a few 980TIs as well, not sure what I'm going to do with them yet. I was running a GTX 980 (non-TI) for a long time.
