Which one is the smarter buy today, not just the cheaper CPU?

Ryzen 9 PRO 7945 is the smarter buy today. Ryzen 9 PRO 7945 is $40 cheaper on MSRP at $409 MSRP versus $449 MSRP, and it gives you a 14.8% average FPS lead across 36 shared CPU game tests in our data. It is also 85.5% better value on MSRP (114.5 vs 61.7 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper. That said, if you already own a compatible AM4 + DDR4 setup, Ryzen 7 5800X can still make sense as a platform-matched option because it avoids a motherboard and RAM swap.

Which one is more future-proof for 2026 and beyond?

Ryzen 9 PRO 7945 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2020), a healthier platform with AM5 and DDR5 instead of AM4, 100% larger total L3 cache (64 MB vs 32 MB), and more multi-core headroom with 12 cores / 24 threads instead of 8/16. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.
