Almost there 
I’d appreciate your advice (again). I’m planning to upgrade in two steps. My MB , RAM and CPU can wait.
I got a proposition (of a dealer) to upgrade my Case, PSU and GPU for now.
As this case will be bigger I can choose a bigger GPU (size). There are two cards that have my attention.
The MSI GeForce RTX 3060 Ti Gaming X Trio 8GB and the Asus RoG Strix GeForce RTX 3060 Ti Gaming 8GB.
I wonder if there is anyone who upgrades their GPU to one of these two and if there facing CPU problems. I think my I7-7700 should be able to handle them but is will run at top level.
Thanks for your thoughts / advice
