That is a horrible price for a 1080ti 11gb. I wouldn't pay more than $750 for a 1080ti, so that's about $400 too expensive and ROI will be ridiculous for that kind of price. From that list, it looks like your best options are either RX580, or 1050TI in my opinion. I would honestly search for a better price of 1080ti's though, because that would be the card to go for if you can manage it. The price on these cards seem so arbitrary and you should probably expand your search.
Hey,
Thanks for the suggestion sir , today I checked with another seller and I can get 1080ti OC version for around $800
Buy as you said ROI will be too high.. I am thinking to get ×2 580s and save rest of the money and hold it for another 2-3 months and wait for new Nvidia GPUs to show..if I can get a hands on them otherwise will keep searching for 1080ti below $700 maybe
If you buy GT 1080ti and mine other coins, you may luckily get roi in 1-2 months but currently your max profit daily is 3.58 on whattomine.com (once it was more than 10$ for 2 weeks).
RX580 is great if you don't like risks and prefer stable profit but I suggest you to get RX580 Sapphire nitro edition, this is considered as a best rx580. I have heared that armor version is cheap but very bad in cooling and hashrate too.
Also consider that bitmain is going to release asic for ether, it may change the game.
