It all started when my HDD died and upon opening it up to replace with a new one, managed to drop one of the screws which landed under the motherboard. After effectively stripping it to get it back and taking plenty of pictures along the way was able to re-assemble the computer but something was different...The display was no longer receiving a signal from the GPU. After a few days of pondering i took it to a computer shop and they blew some air on it and it started working again.
A few days ago it started artifacting and tearing while i was gaming; the next time it was started i was back at square one again so i think i have enough confidence to say it's dead or on it's way out. It has lasted 6 years and has had a good run.
Now i am looking at buying a replacement GPU but being as i am not much of a hardware person, would love some advice on a replacement. I don't have a huge budget as i getting married soon but was thinking around £200 which should get me something mid-range. I currently have a AMD Radeon 7770 GHz Edition but am looking at the AMD RX 570 4GB. I was looking at Nvidia but want to take advantage of my FreeSync monitor which i am currently unable to do.
Motherboard: Pegatron 2AD5
PSU: 600w

Does this look like a good match or would you suggest something else?.
