Quick Answers

So, is Phenom II X6 1045T better than Xeon X5560?

Not really, because they are built for different jobs. Xeon X5560 makes more sense for workstation-style multi-core throughput, while Phenom II X6 1045T 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, Phenom II X6 1045T is the stronger fit. You are getting 0.4% better PassMark, backed by 6 cores and 6 threads.

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

Phenom II X6 1045T still makes the most sense overall. Phenom II X6 1045T comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.4% better PassMark.

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

Phenom II X6 1045T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009) and more multi-core headroom with 6 cores / 6 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
