Hi TJ,
Thanks for your reply. It’s indeed a difficult question to predict or the 3060ti will be future proof. Currently I know my GPU (Gtx1060) is the bottleneck by far. When I do tests my CPU is also a bottleneck, but it manages FS pretty well (80%). As I’m planning to upgrade my CPU and Motherboard later this year I think it won’t be holding back the performance as much as my GPU currently does.
FS bottleneck with my current specs:
FS bottleneck with a RTX 3060 ti (theoretically) 
That said, if also requires a good optimization strategy.
Overall every simmer has the problem (and challenge) to choose the best possible parts with a limited budget.
