Pulse OC has Dual Bios
Are you sure?
I was looking on youtube unboxing and there is no switch on Pulse OC. Nitro+ has it.
The RX 5xx series is still unavailable in Czech Republic, only some of them are in stocks. So price are higher, Nitro+ 4GB cost same as ASUS RX 480 Dual 4GB I'm not sure if it worth to buy 570 over 480. I read that Asus RX 480 dual isn't good in overcloking and doesn't have dual bios.
Is it worth to buy RX 5xx series? The RX 470 cost more than RX 570 here. What brand can you recommend me please? Thanks.
