AMD Radeon RX 580 4GB - Sapphire or Gigabyte?

[Calummullen]

Hey,
I'm finishing off building a gaming PC and I'm going to buy the RX 580 for it. This is my first build and as such I've never bought a GPU before. Are there any differences between the 2 listed, or any of the others available?

Thanks

Sapphire has the best AMD cards , I have the 580 8GB Nitro+ Limited Edition.
