Should I upgrade my GPU or RAM first for gaming?

Upgrade your GPU first, every time. A GPU upgrade from an RTX 3060 to a 4070 gives 40-60% more frames and enables ray tracing, while going from DDR4 to DDR5 RAM yields only 5-10% improvement in some games and often zero in others. One transforms your experience; the other is a nice-to-have if you’re building new anyway.
