I build around test data, not hype. Here are a few things buyers often get told, and what independent testing from Hardware Unboxed and Gamers Nexus actually shows.
MythMore CPU cores means better gaming.
Games care far more about per-core speed and architecture than core count. Hardware Unboxed found only about 4–5% between 6-core and 8-core Ryzen chips of the same generation, and a modern 6-core beat an older 16-core flagship. For a gaming build, that money usually does more on the graphics card.

On AM5, DDR5-6000 CL30 is the sweet spot. Hardware Unboxed measured DDR5-8000 at only about 1–2% faster on average than good DDR5-6000, because past 6000 the memory controller drops to a 2:1 ratio. X3D CPUs are even less sensitive to memory speed.

Gamers Nexus tested a roughly $52 360mm AIO that ran only about 3°C warmer than the best-performing liquid cooler at the same noise level. Expensive AIOs mostly add screens, RGB and nicer build quality, not big temperature gains. Radiator size, fan tuning and case airflow matter more than price.

X3D chips are the fastest gaming CPUs, but the gap shrinks a lot when the graphics card is the limit. Hardware Unboxed shows that at native 4K, or with a mid-range graphics card, most games are GPU-bound and a cheaper CPU often lands close (though CPU-heavy games and upscaling can still favor X3D). They make the most sense with a high-end GPU or high-refresh, CPU-heavy games.

Gamers Nexus tested a pea-sized dot, a big blob, a thin spread and even far too much paste on a desktop CPU. Every method landed within about 1°C of the others, as long as the area over the die was covered. Too much paste is messy, not hotter.

Hardware Unboxed tested the same RTX 5060 Ti with 8GB and 16GB. Once games need more than 8GB, the 8GB card stutters, loses textures or crashes. In one test at 1440p, the 16GB card was 34% faster on average with far better 1% lows. That's why I recommend 16GB cards for 1440p and up.
