NEW PC!

Hi!
Due to recent events I had to do some changes to my gaming rig and in the process of deliberate decision making i.e. I've had a few beers, it's a middle of the night and I've spent past few hoyrs browsing online shops and second hand marketplaces I've arrived at building a mostly brand new PC!
The long and short of it is I had to replace my mobo. Since keeping my old-ass socket CPU was pain in the male donkey I also went with a new one. The new CPU + mobo combo required new RAM I'm DDR5 now, baby!!!. And at the last minute I realised my PSU wouldn't handle the new board. I threw 1TB NVMe SSD to the mix just for the sake of it and now here I am. My wallet bleeds...
Anywho now it's your chances to partake in this frabjous day as I've prepared a little Ouroboros train just to hurt my sad wallet a little more! And there's a little extra Dredge for my 💙
On top of that I'd like to ask y'all what'd you recommend I go ahead and blast on my new creation to fully enjoy all the glorious FPS I can achieve now? You don't have to limit your suggestions to my library, I might as well run my financial situation to the ground since I'm at it...
A second question concerns my performance. I haven't done much testing yet, but I did run Heaven a couple o' times results below and I have my concerns. 1. is the drop in min FPS of 11 in the first run something bad? 2. What about the termals? the CPU stays mostly under 70C but the GPU went right over 80 in both tests, spending most time around 85 with fans going all crazy and occasionally going almost to 90C with fans hitting I believe 100%. Is this expected bahaviour? NGL it's my first time with that class of hardware. I've built a bunch of PCs in the past but typically more low-end and or old systems. This is like the closest to "current-gen" as I've ever been. Is there any way to get those temps and fan speeds down?

man, making trains is so tedious...
If nothing went wrong train's lvl2+ running till the end of the month.
