Quick Answers

So, is Celeron Dual-Core T3100 better than Pentium Extreme Edition 965?

Yes. Celeron Dual-Core T3100 is the better all-around CPU here. It gives you 0.8% better PassMark and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Celeron Dual-Core T3100 has the edge because it leads the single-thread side of this matchup with 160.3% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Celeron Dual-Core T3100 is the stronger fit. You are getting 0.8% better PassMark, backed by 2 cores and 2 threads.

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

Celeron Dual-Core T3100 is still the much better call for a fresh build. Celeron Dual-Core T3100 comes in at an unclear MSRP at unclear MSRP versus $999 MSRP, and it still gives you 0.8% higher PassMark. Pentium Extreme Edition 965 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2006 platform. Even with 100.0% better value on paper (1.2 vs 0.0 PassMark/$), 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?

Celeron Dual-Core T3100 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 2 cores / 2 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
