So, I'm looking at building a pc. I'm thinking of two gtx 1080's in sli. I don't play in anything more then 1080p usually, but I would like room to go further. If i want to buy 4k in the future I would like to, though this build is more for resolutions 2k and under. Will these two cards be fine for this? Or should I wait for the 1080 TI?
