Nvidia CEO Jensen Huang famously remarked, “The more you buy, the more you save,” but as PC users, spending the most can often cause the most headaches. It might sound counterintuitive, since performance and features typically scale with price, even if the relationship doesn’t stay linear. However, buying the most expensive PC upgrades can actually be worse, especially if your rig isn’t prepared for them. Flagship CPUs, OLED monitors, and the fastest RAM can offer the best performance on the market, but only under ideal conditions. In some scenarios, these components can be more trouble than they’re worth.
