Quick Answers

So, is Xeon 5150 better than Core i3-540?

Not really, because they are built for different jobs. Xeon 5150 makes more sense for workstation-style multi-core throughput, while Core i3-540 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon 5150 is the better pick. According to our tests, it delivers 2.1% more average FPS across 48 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Xeon 5150 is the stronger fit. You are getting 0.1% better PassMark, backed by 2 cores and 2 threads.

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

Xeon 5150 is still the much better call for a fresh build. Xeon 5150 comes in at an unclear MSRP at unclear MSRP versus $133 MSRP, and it still gives you a 2.1% average FPS lead across 48 shared CPU game tests in our data. Core i3-540 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (11.7 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1156.

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

Core i3-540 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2006). That makes it the safer long-term bet.
