And Most Importantly, Why Are You Upgrading: I've been putting off a GPU and RAM upgrade for awhile since I needed a new mobo for the DDR4 ram and If I did that I would have needed a new CPU also and up till this point my build has honestly kept up with what I've wanted it to do, but I've noticed the past few months I'm having to lower my settings and well my CPU is 6 generations outdated now and my GPU is 5 years old so I think the time is now ahead of the RTX 3000 launch which I will be getting a 3070/80 when the stock is available.

Do you think the parts above are suitable for the 3000 series and that they are a good choice with the case ect? I'd like to not have to upgrade again for a few years, unless its just adding more ram.
