Which GPU is best for minning now a days?
Don't buy 3800 and 3900 video cards if you are a beginner. But best of all, wait 3 months for news about the end of Ethereum mining. If this happens, then the price of video cards will begin to fall sharply.
If the news goes like this ' Ethereum mining algorithm is here to stay ' I bet that mining difficulty will rise once again and GPU price might increase again, I believe the fear of Ethereum 2.0 is why many are getting out of the games right now.
Now miners do not buy a lot of video cards, because the payback period for equipment is long and there are risks of the end of Ethereum mining. If Ethereum costs more than $5,000, demand may increase. But miners with expensive electricity are forced to leave.
