Thank you for this! This is finally a really good explanation. The hellhound 7800xt is cooler and quieter then the pulse 7700xt in the review from techpowerup.
+ The hellhound is more expensive then the pulse because it got sold out in a shop where it was 490 euro's (almost same price then sapphire pulse).
However... The hellhound itself, physically, may not be that interesting.
Sapphire indeed is the OG partner. I've already seen you can for instance replace the fans without any problem. They got really good support as well AND you can take off the shroud appart from the rest without taking the whole heatpipeline with it.
Hellhound may cool better but indeed that doesn't mean that it is better overal.
Nitro is the best one from sapphire, however, here in this country, availability is a problem as well as pricing. Pulse comes in at 489 euro's while nitro would be around 550 euro's and the red devil is around that as well. If I pay that much, then I would be better of with the pulse 7800xt which is 590 euro's.
However I don't have that much money and I play 1080p 144hz anyway.
I do wanna keep the card for as long as possible though. Therefore, pulse wins. It has better buildquality I think. And if it has something, then I can contact support easy...
