Why go all over the place on different sites, as opposed to simply on this page:

This is the highest clocked RX580 there is, and it maxes out, in boost mode, on the torture test, at 237.4W
That comes close to, but not quite, doubling a STOCK clocked GTX 1060 at 122W (ergo 2x = 244). Board partners clock some models higher, and they go as high as 133 (ergo 2x = 266).
I just think it was disingenuous to take the maximum overclocked version of the RX580 and use a stock-clocked GTX 1060 as a comparison.
That said, when I last wrote, there were 7 or 8 different RX 580 8GB models available for $199.99, only ONE GTX 1060 6GB available for $229.99, and the rest were $249.99 or higher (using PC Part Picker).
I don't calculate the whole system. Buying a video card, compared to the $200 RX 580 8GB, the GTX 1060 6GB goes for a $230 model that is 15% more than an RX 580, and a $250 model would be 25% more.
Today, there's an RX 580 8GB for $180, 4 different ones for $200, and one for $205. Today, there 4 GTX 1060 cards available for $230, one for $240, and the rest $250 and up.
Really, it all boils down to this:
- OVERALL, the RX 580 8GB performs slightly better than the GTX 1060 GB, particularly with newer games as AMD typically favors DX12 and Nvidia typically favors DX11.
- *IF* a new monitor is in the future, a FreeSync monitor is significantly cheaper than a GSync monitor.
- The GTX 1060 6GB is far more power efficient.
You can get the GTX 1060 6GB, but you give up a small amount of performance, and you pay a bit more for it.
At the moment, anyway.
The holidays approach. That wll change day by day.
On the other hand, here's a convenient link for PC Part Picker that shows the cards, sorted in price order, of the various RX 580 8GB and GTX 1060 6GB cards out there.
