I'll be going VR, hopefully very soon, and I'll need a new gfx card. I've pretty much settled on getting a GTX 1080. I thought they were supposed to be $600, but I haven't found any that "cheap". I have found a few around, but there seem to be two design approaches. There is the one fan version that exhausts the hot air out of the case. I kind of like that idea, but with four case fans, I don't have much of a problem with internal temperatures, and I'm pretty sure the GTX 1080 will run cooler than my dual GTX 970s. The other design uses multiple fans that just blow the air inside the case. I'll buy an overclocked or superclocked stock unit, but I generally don't mess around with over clocking myself. I tried it with my 4790K, using low settings with the motherboard app, and my system became unstable.
My plans are to use this for both Gen 1 VR and a 2560x1440 monitor at 60hz. I may get a 4K monitor as well. I expect this card will last me 2-3 years, at which point I may require an entire system upgrade depending on what happens with Gen 2 VR.
So I'm basically wondering if there is a reason to avoid the single fan versions, or if the multiple fan versions are significantly better?
