    Quick Answers

    So, is Ryzen 9 5900X better than Core 2 Extreme QX9770?
    Yes. Ryzen 9 5900X is the better all-around CPU here. It gives you a 207.8% average FPS lead across 50 shared CPU game tests in our data, 854.5% better Cinebench R23 multi-core, 744.8% higher PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.
    Which one is better for gaming?
    If gaming is the priority, Ryzen 9 5900X is the better pick. According to our tests, it delivers 207.8% more average FPS across 50 shared CPU game tests.
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, Ryzen 9 5900X is the stronger fit. You are getting 854.5% better Cinebench R23 multi-core, backed by 12 cores and 24 threads.
    Which one is the smarter buy today, not just the cheaper CPU?
    Ryzen 9 5900X is the better buy right now. Ryzen 9 5900X comes in $850 cheaper on MSRP at $549 MSRP versus $1,399 MSRP, and it still gives you a 207.8% average FPS lead across 50 shared CPU game tests in our data. It is also 2052.8% better value on MSRP (71.0 vs 3.3 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
    Which one is more future-proof for 2026 and beyond?
