I have a somewhat old PC (a 9th generation i3 with an RX 6500 XT). I've saved up a bit of money and I'm thinking of upgrading it, but I can only afford to change the processor and either the motherboard or the graphics card. What should I do? Depending on which one I upgrade, I'll upgrade the other later. Or maybe I should save up more and build a new PC from scratch? But the price of RAM is putting me off. I was thinking of changing the processor to an i3 14400f and getting a DDR4-compatible motherboard so I could reuse the RAM I already have. Is this worth doing?
