Now is clearly.
but sometimes I'm feel confusing, newest PBE version come s with one click strap copy but many people here still trying to flashing their Polaris cards with downloaded bios from anywhere.
Probably because those straps have their own set of problems sometimes?
If you read posts here a lot, you'll often find that people sometime get unstable
cards after using one-click bios patch straps
we would get more experience from those, for example, 4GB Polaris cards would more stable with copying strap 1500, so we could use PBE 1.6.6 and so on. after getting much experience we would good enough for using manually copy strap of PBE.
