I currently have a Geforce 770 4GB with a 4670k. I want to play the new Doom at full settings and have buttery smooth framerates. I've been waiting a bit now to snag a 1080 (non-FE) to pair with a 6700k so I can do so, while simultaneously giving my son my hand me down rig which will be an upgrade from his 3570k+750Ti 2gb.
I've been trying to find some info on when the 1080 are expected to be released in sufficient quantities that I can buy one without paying massively inflated over MSRP prices. Have there been any credible rumors on when this would likely happen or should I just suck it up and grab a 1070 and save a few bucks while im at it?
Don't waste your $$ on the GTX1080 period. Many people on this forum just want the best videocard
regardless of the cost. You are going to have a disproportionate amount of gamers who will pay hundreds of dollars more for 20% more performance because they want the best. They would have bought the 1080 even if it cost $799 or $899. These gamers will have the next best card in 12-15 months. Given that you have a 770 still, it's clear that you do not fall into this consumer category. You are better off grabbing a 1070/980Ti and then when you need a card 75-100% faster, just get that in 2018-2019. If you held on to your 770 for that long, you are willing compromise on performance. That means you can just turn down a couple settings and enjoy 1070/980Ti 95% as much. The 1080 will not be any more future proof than a 1070 (this is a fact that goes back to GTX470 vs. 480, 570 vs. 580, 670 vs. 680, 970 vs. 980) either because it doesn't have true DX12 hardware (Volta should).
If you want to future-proof and max out games at 1440p 60-144Hz and 4K performance, you go GTX1070 SLI. In cases where 1080 is faster than a 1070, it won't be fast enough to make any tangible difference but 1070 SLI actually will.
For Doom, in particular, you do not even need a GTX1070. If you are only gaming at 1080p 60Hz, RX480 for $240 is enough.
Even for 1440p, RX 480 will slice through Doom.
Alternatively, MSI Armor 2X 980Ti for
$365 (or even less with a $25 PayPal code) is a great deal. In comparison a $600-700 1080 is a horrible deal because 1080 max OC is only 25-30% faster than a 980Ti max OC but you are paying through the nose to say you have the fastest.

Bottom line is, high-end $600-700 cards are not worth it unless money isn't a factor OR you plan to upgrade
every generation OR you are retired and gaming is your #1 hobby.
$500 680 -> 2.5 years later we could buy a $275 R9 290
$550 980 -> less than 2 years later you can get a 1060 for $250.
$650 Fury X / 980Ti -> a year later we can get a $365 980Ti
Unless you don't care about $, or make enough $ to not care or want the best
every year, don't buy the 1080. In fact, if you want to spend that much $, get a 1070 now and then next year just get the 1080Ti.
