I Decided to Upgrade my Hardware. Luckily i die that before the Prices wenn Up so i was able to get a 3070 for 650 €. I also upgraded the Case and CPU due to the fact i wanted to build a secound rig in my 011 air.

collected pakaging of old and new stuff I used for PCs
(the Gainward GTX 580 one is my favorite)

Got a new Ryzen 7 2700 :). Unfortunately, there seems to be a problem with the Phases on my Rog Strix x470 (can't get a higher clock than 3,75 GhZ allcore). I'll get a new x570 Board soon to get overclocking again.

Got some Cooler Master Masterfan MF140R ARGB to change up the airflow in my case. I got rid of 12 120mm Eiszyklon Fans and put in 4 Masterfans. Obviously my PC is much quieter now. The temps are a little bit higher but it is a maximum difference of 5° C. I also put in some cheap LED strips because my case was alot darker with less fans :D.
