Looks like some of the Nvidia GTX 1080 reviews are hitting the intertubes. Toms Hardware and, my personal favorite, ArsTechnica have published their reviews and the results are detailed and intriguing. Anandtech only has their preview up at the moment.
EDIT: I have to give a nod to Toms Hardware for providing the better article.
I am on the graphic card upgrade path from a GTX 970, hoping to get a VM set in the fall, and the 1080 looks to be, dare I say it, a good target with a potentially long life span. Seeing as the GTX 970 I have is on the low side for VR applications (flight simming immersion being the main driver for most of my hardware purchases), I may be wrong in thinking that the 1080 will suffice for a couple of years… maybe
I think it would definitely be worth waiting for pure gaming benchmarking in titles we play as a group here if coming from a 970/980. A lot of the things that we like are CPU bound rather than GPU, so like you said - unless we’re getting new monitors and headsets at the same time then it is tempting to wait just a bit more.
