I’m upgrading my 4gb AMD Radeon RX 6500 XT to a 12gb ASRock AMD Radeon RX 7700 Challenger and I have an AMD Ryzen 5 5000 series CPU. My friend is telling me there will be a really bad bottlenecking issue but I’ve been looking into it for a bit and it doesn’t seem like it will be devastating as he says. Should I get a new CPU with it or could I wait?
