Quick Answers

So, is Core 2 Duo P8800 better than Xeon X5492?

Not really, because they are built for different jobs. Xeon X5492 makes more sense for workstation-style multi-core throughput, while Core 2 Duo P8800 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core 2 Duo P8800 is the stronger fit. You are getting 0.7% better PassMark, backed by 2 cores and 2 threads.

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

Core 2 Duo P8800 still makes the most sense overall. Core 2 Duo P8800 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.7% better PassMark.

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

Core 2 Duo P8800 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2009 vs 2008). That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
