Mining has made the 480 and 580 nearly impossible to get without paying way more than they are worth to gamers. Your best bet is to wait it out or purchase a Vega or lower end AMD video card
The prices seem to have stabilized somewhat here in the states. 4Gb versions of the RX 580 can be had for as low as $259
While the 8Gb version is currently bottoms out at $289.99 which isn't a bad deal really.
For the Vega 56, you will be looking at $499, while the Vega 64 currently bottoms out at $619 for the air edition. I think at this juncture the Vega GPUs are a bit more price inflated than the Polaris based RX 580s.

Take a looksie here: ▷ Gigabyte Radeon RX 580 Gaming 4096MB GDDR5 PCI-Express Graph… | OcUK
Not that bad a price to be honest. ASUS DUAL RX580 OC 4GB - Graphics Card | Alza.co.uk as well is decent pricing if you want to buy a rx580.
Thanks all for answers. Today I got Sapphire Nitro+ RX580 from my job-colleague. Now I am happy again, because I can play again
