So, you were excited to buy one of the best CPUs in the world. It came with a huge price tag, but you convinced yourself that you'd actually utilize all that extra performance. Maybe you bought it as a "just in case" investment, hoping to use all those cores someday. Maybe you expected more cores to net you more FPS in your favorite games. You might even have bought a Ryzen X3D CPU hoping to outshine every other chip on the market. However, the best laid plans often go awry, especially when you overspend on something that you never end up using. Here are three telltale signs that you wasted money on that expensive CPU.

You invested in 8+ cores for gaming

Your high-end CPU is a mere spectator

Modern games have become more CPU-intensive than before, but they still fail to utilize multicore CPUs effectively. Due to the complexity of distributing game operations across multiple cores and making the associated performance overhead worth it, games are heavily dependent on single-core performance. Sure, you need at least 6 cores in a modern gaming PC, and even 8-core CPUs help improve performance to an extent, especially the 1% and 0.1% lows. That said, going beyond 8 cores on a gaming-focused build is throwing money down the drain.

GPUs still handle the heavy lifting in most games, with the CPU taking care of physics simulations, game logic, and AI behavior. As 1440p adoption grows and 4K becomes more affordable, thanks to modern mid-range GPUs and cheaper 4K displays, high-end CPUs don't justify the premium. If you're strictly after peak gaming performance, investing in the best GPU you can get is still the best strategy. Other components, such as the CPU, RAM, and storage, don't need to be top-tier to guarantee a high-end gaming experience. Instead of fixating on the 12 or 16 cores, you could get an 8-core Ryzen X3D CPU instead. That said, you'd still need ideal conditions to make the most of these gaming-focused chips.

You paired a Ryzen X3D CPU with a budget or mid-range GPU

Rookie mistake, if I ever saw one

As I mentioned in the previous section, CPUs like the Ryzen 7 9800X3D or Ryzen 9 9950X3D need ideal conditions to deliver the performance they're famous for. Most people who buy mid-range GPUs like the RX 9070 or RTX 5070 can't expect to drop in a Ryzen 7 9800X3D and beat every other gaming PC on the market. Benchmarks by Hardware Unboxed have shown that the Ryzen 7 9800X3D offers a mere 7–8% more FPS than the Ryzen 5 7600X when each of them is paired with the RX 9070. Only when you pair them with, say, an RTX 5090 or RTX 5080 does the difference in performance become noticeable. Even the 1% lows are almost identical when GPUs like the RX 9070 are in the picture.

If you spent around $450 (or more) on a Ryzen X3D CPU, you can't justify the investment without also splurging on a $1,000 GPU (which really costs $1,200–$1,300 in this market). The Ryzen X3D CPUs are great at what they do, but they aren't magic. You still need a top-tier GPU to bring out the performance you paid all that money for. If you're not planning to buy a high-end GPU, then getting a 6-core chip like the Ryzen 5 7600 or Ryzen 5 9600X is the way to go.

You don't run multicore workloads regularly

Save the money for other components

Having more CPU cores isn't always a waste, but you need to run the right applications to fully use them. Gaming is far from the ideal multicore workload, and doesn't need more than 6 cores even in 2026. If you aren't regularly running programs like Photoshop, Premiere Pro, Blender, Cinema 4D, or heavy scientific and AI workloads on your PC, then that 12-core or 16-core chip isn't going to offer you any benefits, certainly not ones that will justify the cost. You might think you need extra cores for the occasional productivity indulgence, but an 8-core CPU can easily see you through if you're not a professional or otherwise heavy multicore user. It's best to skip high-end CPUs and invest in a better GPU, more RAM, faster storage, or other components instead.

Don't waste money on performance you'll never use

It can be tempting to splurge on high-core-count CPUs, but what good are they if they don't deliver? If your only requirement is high-end gaming, then you don't need to spend over $200–$250 on a modern CPU. Even the Ryzen X3D CPUs won't make a difference to gaming performance unless you pair them with a flagship-grade graphics card. Unless you know you'll be utilizing all those extra cores, high-end chips are not for you. It's better to invest your budget in components that will have a real impact on performance, such as a faster GPU.
