I'm an everyday guy, I'll probably just screenshot every single piece of scenery around and send it to my friends to convince them to buy the game. And then download whichever inevitable mod that turns Johnny Silverhand into Theodore Logan.
However, if I somehow win the GPU in this contest, I will come back to tell people how much I love playing the game in high-res and post screenshots where the graphics are obviously set to Low, and play dumb when people point it out. "That's not 4K!" "I know, man, the jpeg is like 131 KB! Must be the crazy high resolution!"
