Very similar specs to mine (although newer generation processor).
Can tell you you'll be pleasantly surprised, I've been really impressed, not just with the performance of the RX 9070xt, but also how completely stable it is. As someone who was really put off with AMD's graphics drivers from what I'd heard for quite a long time, they've done a fantastic job of getting back on track.
That monitor as well will knock you a little, HDR1000 is a SIGNIFICANT improvement, and that monitor has true backzone support.
That all sounds amazing! I can't wait to be reborn and have my eyes opened once again! I've never really been a fan of AMD either but they have persevered and produced some real bangers lately.
