AMD Ryzen 7 7800X3D.

Below are some options based on your requirements:

1. AMD Ryzen 9 7900X:

   • Pros: Strong multi-core performance, good value-to-performance ratio, plenty of headroom for the RTX 4060 Ti (and beyond).
   • Cons: A little pricey for some.
   • The Ryzen 9 7900X offers 8 cores and 16 threads with a boost clock speed of 5.6 GHz. It’s a solid choice for both gaming and productivity tasks. If you’re willing to invest a bit more, this CPU provides excellent performance and future-proofing.

2. Intel Core i5-13600K:

   • Pros: Good gaming performance, competitive pricing.
   • Cons: Fewer cores than the Ryzen 9.
   • The i5-13600K is a 6-core, 12-thread CPU with a boost clock speed of 5.0 GHz. While it has fewer cores, it still performs well in gaming and multitasking scenarios. It’s a budget-friendly option that pairs nicely with the RTX 4060 Ti.

3. AMD Ryzen 5 7600X:

   • Pros: Good mid-range performance, reasonable price.
   • Cons: Fewer cores than the Ryzen 9.
   • The Ryzen 5 7600X offers 6 cores and 12 threads with a boost clock speed of 4.8 GHz. It strikes a balance between performance and cost, making it suitable for gaming and multitasking. Consider this if you want a more affordable option.

4. Intel Core i5-13400F:

   • Pros: Good gaming performance, budget-friendly.
   • Cons: No integrated graphics.
   • The i5-13400F is a 6-core, 12-thread CPU with a boost clock speed of 4.2 GHz. It lacks integrated graphics but provides solid gaming performance. If you’re on a tight budget, this CPU is worth considering.

Remember that future-proofing involves considering not only the current GPU but also potential upgrades down the line. Both the Ryzen 9 7900X and the Intel Core i5-13600K offer good performance and room for growth. As for the motherboard, the x670E/B650E should work well with an NVIDIA GPU, but always check for compatibility and features specific to your needs.

Ultimately, the choice depends on your budget, preferences, and long-term goals. Consider your use case, whether you prioritize gaming, streaming, or multitasking, and make an informed decision.

Tbh at 1440p and 4K the NVIDIA GeForce RTX 4060 Ti is gonna be the bottleneck way before your CPU is. Spending a fortune on a Ryzen 9 is basically overkill if you are just gaming and streaming. I have built a few mid-range setups recently and usually suggest putting that extra cash toward a better GPU or more storage instead.

• AMD Ryzen 5 7600 is arguably the best value right now. It handles the 4060 Ti perfectly and the AM5 platform gives you an easy upgrade path later.
• Intel Core i5-13400F is another solid budget move. The extra E-cores help with streaming and background apps without breaking the bank.
• Use the comparison tools on TechPowerUp or check out the Hardware Unboxed scaling videos on YouTube. They show that at higher resolutions the gap between a mid-range and high-end CPU is almost zero. Dont worry about the motherboard combo. Nvidia cards work fine on B650 boards. Unless you need a ton of PCIe 5.0 lanes for specific work stuff, a basic MSI MAG B650 TOMAHAWK WIFI will save you plenty of money over those expensive E-series boards.
