I am trying to decide between the Powercolor Red Devil 5700XT and the Sapphire Nitro + 5700Xt .
I have heard many having faults with the Sapphire Nitro + but none so far from REd DEvil ...which is better ?
Both have identical performance, both being 3% faster than the reference RX 5700XT. The PowerColor model is slightly more efficient (9w under gaming conditions), slightly quieter (2dB under gaming conditions), and is slightly cheaper ($10 on Newegg), so realistically they are identical cards as the differences are so close they're within the margin of error. They both feature the same 2 year warranty as well.
I use Sapphire Nitro cards and I have not had issues with them at all.
I use the cards with dual fans which are efficient, but some extreme cards have 3 fans
Everything fits my chassis, the HAF 932 is room room in spades for video cards galore
