Replaced my 3090 FE with an ASUS Dual 4070 Super OC. Almost identical performance for way less powerdraw + fancy new features like Framegeneration.

Added two more 8GB sticks to have 32 in total now.

Got a nice deal on a 5800X3D. I assume I wont need a new Upgrade for a very long time.

My previous 650 Watt PSU could'nt keep up with the 3090's powerdraw, so I upgraded to a 1000 Watt one. While I was at it, I also changed the case to an airflow one. The GPU, especially the VRAM got way too hot in my old case, but I was able to bring down the temperatures by 10-15 degrees on average!

Replaced the 3070 for a 3090 FE which I found on Ebay for a very low price. Works flawless and allows me to not care about graphic settings in games anymore. I will definitely look more into used hardware from now on, especially with recent GPU prices.
