Really cus my G1 does 500+ easy. Im pretty sure if you get your hands on a good 1070 it could come close to a 1080 maybe within 5%.
Mind you electricity for me is free though but I dont want to invest a lot (wont be buying the Vega cards anytime soon).
I'd stick with 1080Ti or 1070 and forget about the 1080.
I have never seen a 1070 that managed more than about 460 - SPECIFICALLY INCLUDING my Gigabyte G1 cards.
You apparently have one that handles a lot higher overclocks better than most do, or you're looking at the "momentary peaks" and counting those as the hashrate where I tend to look at the AVERAGE hashrate instead, or you're in a VERY COLD ambient temp with your cards - or a combination of all 3.
Even with minimal tuning and having "fairly high ambient temp cooling" limitations, most of my 1080 cards easily hit 530 and I suspect when I take the time to fine-tune them they will be able to push closer to 550 - and NONE of those are "high end" 1080 models, most are the Zotac Mini or the bottom-end Gigabyte 2-fan models which are definitely heat limited in my environment.
On the other hand, with 1070 pricing getting back down into the pre-gouge range, the 1070 is starting to look like a better option even at the system level to the 1080 in many respects - and the recent climb in 1080ti pricing isn't helping any.
Completely agree on the 1070s being the best bang for buck currently
https://goo.gl/7s7Kb6I've ordered a couple of these well . . because I like the white xD but the zotac mini and now a couple other cards have come down as well to the 400 price which is pretty nice to see.
1080 TI are still stupid priced and it's really deterring my interest in them, looking forward to when they come back down to reality // the 1060s are a good price now as well
What are your preferred settings for getting max performance out of your cards? You probably tune them down a bit like me due to heat issues?
Also does anyone know what the ideal ambient temp is for operating GPUs?
