Quick Answers

So, is Core 2 Quad Q9000 better than Athlon 64 X2 5400+?

It depends on what you want from the system. For gaming, Athlon 64 X2 5400+ is ahead with a 1.6% average FPS lead across 48 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Quad Q9000 pulls ahead with 0.8% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core 2 Quad Q9000 is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 4 threads.

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

Core 2 Quad Q9000 is the better buy right now. Core 2 Quad Q9000 comes in $137 cheaper on MSRP at $348 MSRP versus $485 MSRP, and it still gives you 0.8% better PassMark. The compromise is that Athlon 64 X2 5400+ is still the better pure gaming CPU with a 1.6% average FPS lead across 48 shared CPU game tests in our data. It is also 40.4% better value on MSRP (4.6 vs 3.3 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core 2 Quad Q9000 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2009 vs 2006) and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
