I have no clue when it comes to all this stuff, but I got a used Zotac 1080ti AMP edition card. At first I thought it wasn't working because the fans weren't coming on but I guess that is a feature that they don't kick in until needed when the temps get higher lol.
Here's a pic of it on idle...
Right now my system is getting a little long in the tooth but it's still holding up fairly well so I am not ready to do a full new build.
Right now my main components are
Intel Core i5-2500K OC'd to 4.2Ghz
16gb CORSAIR Vengeance DDR3 1600(PC3 12800)
Nvidia GTX 780
Acer GD245HQ
500gb Samsung...
