I have some questions about Ryzen 5700X3D+RTX 5080 64gb ddr4 PC vs 7800X3D+RTX 4080 32gb DDR5 PC

Which one will perform better and which one do you think will sell better. They are separate PC listings on Facebook marketplace and I am thinking of picking up one to flip. Both are the same specs besides the CPU, ram, and GPU. Same 850w PSU and 2tb SSD, they are listed at 1600$ USD. I was thinking of selling either PC for about 2500$ USD after rebuilding them into nicer cases
