after playing Witcher 3 for the past few hours on ultra I have noticed my GPU is getting a work out. Asus gtx 780 at its max stable oc.
It is running 35-45FPS which im good and frankly impressed with, but it runs hot, which i expected, but hot enough where im questioning if i should water cool the gpu

max temp ive seen so far is 85C in high desity areas, all my case fans a gpu fans went into turbo and after a few min it settled at 77.
i havent noticed any screen artifacts or throttling.

I have never water cooled a GPU before just CPUs, looked at my options, i could either spend 100$ on a NZXT g10 and x41
cooler, spend 500$ on ekwb parts, or spend 600$ on on Asus GTX 980. obviously I like the 100$ option, but im looking for real world results, for dropping temps and if there is room maybe squeezing i bit more OC from the card, if anyone could provide insight that would be great.
