Quick Answers

So, is Core 2 Duo T9600 better than Pentium Extreme Edition 955?

It depends on what you want from the system. For gaming, Core 2 Duo T9600 is ahead with a 1.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium Extreme Edition 955 pulls ahead with 0.7% better PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium Extreme Edition 955 is the stronger fit. You are getting 0.7% better PassMark, backed by 2 cores and 4 threads.

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

Core 2 Duo T9600 is still the much better call for a fresh build. Core 2 Duo T9600 comes in at an unclear MSRP at unclear MSRP versus $999 MSRP, and it still gives you a 1.8% average FPS lead across 50 shared CPU game tests in our data. Pentium Extreme Edition 955 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2005 platform. Even with 100.0% better value on paper (1.1 vs 0.0 PassMark/$), 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?

Core 2 Duo T9600 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2008 vs 2005). That makes it the safer long-term bet.
