Choose a CPU compatible with 1440p or 4K resolution.
You're starting this build for the first time and looking to upgrade from 1080p. You're considering splurging on 4K or even 1440p, depending on monitor availability. For gaming and web use, a solid CPU choice would be one that balances performance and efficiency. Look for processors with strong multi-core support and good thermal management—something like an Intel Core i5 or AMD Ryzen 5 series would work well here.
It doesn't really matter how high the resolution is. The more detailed it gets, the more demanding it becomes for the GPS, though the CPU handles the task similarly. For the refresh rate you plan, the CPU plays a bigger role. Still, as resolutions rise, the GPU struggles to process the frames quickly, which can lead to similar performance across different CPUs. You'll just need a suitable CPU for the games you enjoy, with the GPU being the main focus.
Generally, the most important part when increasing resolution to 4K is the graphics card and ensuring it has sufficient onboard video memory—typically between 8 to 16GB. NOTE THAT not all cards support the same memory bus width. A 128-bit bus won’t perform well regardless of how much RAM you have. It’s advisable to aim for at least a 256-bit bus, recommending 384-bit or even 512-bit options. Personally, I prefer HBM cards with 4096-bit buses. Choose an "8" series card rather than a "7" like the 5800 versus the 5700 or 2080 compared to the 2070. Cards from the 8 series are usually top quality. It also matters what games you plan to play in 4K, since not all games demand the same level of CPU power. Your current CPU appears sufficient based on its passmark score (see: https://www.cpubenchmark.net/high_end_cpus.html), placing it among the best. In my opinion, upgrading your graphics card is more crucial for achieving smooth 4K performance. If you haven’t tried running 4K yet, consider it—your specs suggest it could work well. Just keep in mind that a more powerful PSU is necessary; for example, if your system needs around 573W, a 600W unit will run it efficiently and prevent overheating, whereas using less than required can cause excessive heat and reduce lifespan.
I plan to construct an entirely new setup. I've played Apex, PUBG, Siege and Cod Warzone at 4K using the 3600x and 5700xt resolutions, which performed adequately. I maintained over 40fps without needing extreme settings. My existing RX 850 watt PSU is ready to fit into this new configuration. I'm deciding on the CPU first—clearly a more affordable option lets me allocate funds to the GPU. Was a Ryzen 2600x sufficient if paired with an RTX 2080 Super?
