Quick Answers

So, is Core 2 Duo T5670 better than Core i7-965?

It depends on what you want from the system. For gaming, Core i7-965 is ahead with a 15.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Duo T5670 pulls ahead with 0.5% better PassMark. Core i7-965 also has the bigger cache pool with 300% larger total L3 cache (8 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Core 2 Duo T5670 is the stronger fit. You are getting 0.5% better PassMark, backed by 2 cores and 2 threads.

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

Core 2 Duo T5670 is still the much better call for a fresh build. Core 2 Duo T5670 comes in at an unclear MSRP at unclear MSRP versus $1,000 MSRP, and it still gives you 0.5% better PassMark. Core i7-965 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 100.0% better value on paper (3.4 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1366.

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

Core i7-965 is the safer long-term CPU choice because it gives you more room to grow and a better platform outlook.
