Good thinking. If you can go higher on the CPU, I would recommend it- it’ll bottleneck your GPU as is. I’d go for a 5800 or 5900, or even a 5950, whatever your budget is
Oh man… couple things, and please know that I’m saying this with your best interest at heart:
Don’t buy pre-builts from Best Buy. Ever. They put notoriously bad parts in and they’re infamous for using parts that are incompatible with each other. They also have horrible customer support and they will not help you at all.
They also overcharge, by a LOT. You’re getting ripped off at the moment. These parts:
AMD Ryzen 7 5700G
512GB SSD
16GB RAM
RTX 3060
Shouldn’t be costing you 1050 USD. I could buy that GPU and CPU right now for 547 dollars. 500 dollars for a 512 GB SSD and 16 GB of RAM + case is absolutely ridiculous. I could buy the SSD and the RAM right now for a grand total of 636 USD. A case is about 80, usually, that puts you at 716 USD. You’re overpaying by 300 dollars.
CPU, GPU, RAM, SSD, WiFI motherboard- everything but the case. Everything’s on sale right now. 885 before the case. Same specs as yours, but 1 TB instead of 512 GB. Still 200 dollars cheaper, if you get a cheap case you can probably save 150 and get 512 GB more storage. Merry Christmas
