I've just completed a serious gaming PC upgrade for a client who bought some of the components in France when he was on holiday, where they are usually half the price compared to rip-off Argentina.
From Ryzen 2600, 16GB of RAM, RX 590 to Ryzen 7 5700X3D, RTX 4070 Super, extra 16GB of RAM, NVMe 500GB and an ID Cooling water cooler.
I stripped the PC down to the metal and started from scratch which was very rewarding.
