Ok guys, i finally bought the sapphire pulse rx 550 4gb and i can confirm that worked perfectly (via hdmi) from the first boot (with ddu), without any bios reset without anything with the ga-ma700t-ud3 motherboard. I have an old athlon ii x4 640 and on most aaa games i get the expected fps except -i thing- the metro exodus (avg 28fps low) but in the far cry new dawn i get 35-40 with medium settings and in witcher 3 i get 30-35. Ok its nothing special but from the gt520 its day and night !!
I've been far far from minimum specs but i wonder if i try to play the cyberpunk 2077 how many fps i will get, below 20 ?? Or i have a change to get around 25-26 ??
