Quick Answers

So, is Xeon E5606 better than Phenom II X4 850?

Not really, because they are built for different jobs. Xeon E5606 makes more sense for workstation-style multi-core throughput, while Phenom II X4 850 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, Xeon E5606 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 4 threads.

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

Xeon E5606 still makes the most sense overall. Xeon E5606 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.1% better PassMark.

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

Xeon E5606 makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 4 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
