Quick Answers

So, is Xeon E5462 better than Core 2 Quad Q9450?

Not really, because they are built for different jobs. Xeon E5462 makes more sense for workstation-style multi-core throughput, while Core 2 Quad Q9450 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 E5462 is the better pick. According to our tests, it delivers 0.1% 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, Xeon E5462 is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 4 threads.

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

Xeon E5462 is still the much better call for a fresh build. Xeon E5462 comes in 8.2% more expensive on MSRP at $342 MSRP versus $316 MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data. Core 2 Quad Q9450 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 8.0% better value on paper (7.0 vs 6.5 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

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

Core 2 Quad Q9450 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2008 vs 2007). That makes it the safer long-term bet.
