If it's one thing that bugs me the most about the recent surge in Crypto is that two years ago I had been watching hundreds of videos about BTC mining, really interested in it when I decided that mining it was a waste of time and that I should just use Bitcoins for payments. I don't want to make that mistake again. I'm not the most knowledgeable on the subject, so I'm after a little advice. I've seen that all of the popular AMD GPU's have gone out of stock, due to a sudden surge in people mining coins, meaning that if I want to go down the RX 580 route I'll have to wait just under two months. I also understand that ETH may soon become PoS (Meaning it can't be GPU-mined) which is why I've also been looking at GTX cards for mining Zcash. Anyway, I'm torn between two graphics cards: https://www.scan.co.uk/products/4gb-sapphire-radeon-rx-580-pulse-14nm-polaris-2304-streams-1366mhz-gpu-7000mhz-gddr5-2xdp-2xhdmi-dvi - £250/ $330 - PreOrder for 31'st August. Cost Per Rig: £2000/ $2635 Estimated Monthly Profit: ZEC - $290. ETH - $520 http://www.ebuyer.com/750767-asus-geforce-gtx-1080-turbo-8gb-gddr5x-dual-link-dvi-d-hdmi-displayport-pci-e-turbo-gtx1080-8g - £495/ $650 - Availible now. Cost Per Rig: £3500/ $4600 Estimated Monthly Profit: ZEC - $760. ETH - $380 Remember that those prices are all wild estimates based on the current coin price/ difficulty and could vary massively. I'm looking to get a few rigs and I'm more concerned about daily earnings as opposed to ROI. I know that @aptechfsd's into mining, and has shared his RX 480 set-up before. Which of the two - or other - do you think I should purchase?
