That's so good to hear, well done for persevering.It's been just over 2 weeks from I got the pc back and I'm happy to report its been running faultlessly.
I've played over 30 hrs in warzone since then, and its managing between 140 - 160 fps which is more than I was expecting. Super happy with the build and I'm hoping to take some pictures of my setup over the weekend, it's kinda went a bit crazy.
Thanks again to everyone who provided help and advice to get it sorted.
