I invested in Freesync monitor and now need something better than my current RX 580 to power it. I will likely just buy the Vega 56 once the custom designs come to market, or buy stock version and waterblock, assuming I can find one at $399 USD. People are using the increased power requirements as a major showstopper for not buying Vega. Lets say that if you buy Vega and find out that there is a change in full load power requirements from your old card to Vega of 85W, the cost in additional power is minimal, based on my power costs here in Nevada. If I play 20 hours of gaming a week, I end up paying an additional 20 cents per week (12c per kwh in Nevada) based on calculation wattage x hours used ÷ 1000 x price per kWh= cost of electricity
If I refer to gaming load results at Anandtech, during BF1 gaming, there is a difference of 51W between the RX 580 and the Vega 56 and 142W between the RX 580 and Vega 64, so if I use the example above for calculating additional power costs then the swap to a Vega 56 will cost an additional 12 cents per week and swap to Vega 64 will cost an additional 34 cents per week.
Perhaps my math is wrong? While the talk of increased TDP and power requirements are initially alarming, the additional costs look to be minimal. These increased power requirements won't stop me from buying Vega.
Having said this the additional cost will hurt miners who are using their computers 24/7 to mine.....
