Quick Answers

So, is Core 2 Extreme X7900 better than Athlon II Neo K325?

Yes. Core 2 Extreme X7900 is the better all-around CPU here. It gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data and 0.4% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core 2 Extreme X7900 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, Core 2 Extreme X7900 is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 2 threads.

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

Core 2 Extreme X7900 is still the much better call for a fresh build. Core 2 Extreme X7900 comes in at an unclear MSRP at unclear MSRP versus $60 MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data. Athlon II Neo K325 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (18.5 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on S1.

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

Athlon II Neo K325 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2007). That makes it the safer long-term bet.
