Quick Answers

So, is Phenom II X4 X920 BE better than Core 2 Quad Q8300?

It depends on what you want from the system. For gaming, Core 2 Quad Q8300 is ahead with 8.7% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Phenom II X4 X920 BE pulls ahead with 0.9% better PassMark.

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

For streaming, content creation, and heavier multitasking, Phenom II X4 X920 BE is the stronger fit. You are getting 0.9% better PassMark, backed by 4 cores and 4 threads.

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

Phenom II X4 X920 BE is still the much better call for a fresh build. Phenom II X4 X920 BE comes in at an unclear MSRP at unclear MSRP versus $179 MSRP, and it still gives you 0.9% better PassMark. Core 2 Quad Q8300 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 100.0% better value on paper (10.7 vs 0.0 PassMark/$), 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?

Phenom II X4 X920 BE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2008) and more multi-core headroom with 4 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
