Question about ASUS Z170 Pro Gaming

The Sapphire RX 580 NITRO + (4GB, mid-range) is a sham. A slight revision of the RX480

I would lean more towards a Geforce GTX card.

Palit GeForce GTX 1060 Dual (6GB, mid-range)
or
ASUS GeForce GTX 1060 DUAL O6G (6GB, mid-range)
or
ASUS GeForce GTX 1060 STRIX O6G-GAMING (6GB, mid-range)

@ Eilerf: I'll look at the board you mentioned again and then do the calculation again. Thank you very much!

I have decided on the 5846822. The chip will remain an i7 from Intel board. Thanks for the help!

but it has other motherboards on which ryzen fits...or do you only need a cpu and graphics card and already have the motherboard?
Which cpu did you put in there? the i5 or the i7?
What games do you play?

@ChriZ86: Why is the Rx580 a cheat pack? They simply reworked the Rx480 and got a bit of performance out of it and now sell the 580 for the same price, only you get more performance? It's a good thing, more performance for the same money.

What kind of games do you want to play? Depending on what you want to do, I would recommend a Ryzen 5 (saves you a lot of money and runs really nice, I have one myself).
