Ordered a Sapphire Pulse Vega 56 yesterday and it came this morning very pleased, it has Samsung memory and installed easy,no coil whine. I will be undervolting and overclocking it when I get a chance, I've had a little play and got to say I am very impressed.
I am running it in a system I built about 5 years ago the hd7970 gb edition I had in it died a few days ago so was in need of a gpu, as I don't want to build an entire system again for a year or two.Cpu wise I have a 3770k running 24/7 @ 4.7ghz so that may bottleneck it a bit but initially having tried it on For honor(only game I have installed atm lol)it runs beautifully on extreme settings @ 1440p I was seeing 80 to a 120+ fps. Which having had to play it for a while now on the hd7970 at 1080p on my 1440p monitor on mediumish settings to scrape 60 fps I'm very impressed!
Highly recommend guys for 1440p gaming and I haven't even tinkered with it yet
