Quick Answers

So, is Pro A6-8500B better than Core 2 Quad Q9000?

It depends on what you want from the system. For gaming, Pro A6-8500B is ahead with a 2.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Quad Q9000 pulls ahead with 0.3% 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 0.3% better PassMark, backed by 4 cores and 4 threads.

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

Pro A6-8500B is still the much better call for a fresh build. Pro A6-8500B comes in at an unclear MSRP at unclear MSRP versus $348 MSRP, and it still gives you a 2.2% average FPS lead across 50 shared CPU game tests in our data. Core 2 Quad Q9000 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (4.6 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA478.

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

Pro A6-8500B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2009). That makes it the safer long-term bet.
