Quick Answers

So, is Core 2 Duo T7600 better than Core i3-2120?

Yes. Core 2 Duo T7600 is the better all-around CPU here. It gives you a 3.3% average FPS lead across 50 shared CPU game tests in our data and 1.3% 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 Duo T7600 is the better pick. According to our tests, it delivers 3.3% 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 Duo T7600 is the stronger fit. You are getting 1.3% better PassMark, backed by 2 cores and 2 threads.

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

Core 2 Duo T7600 is still the much better call for a fresh build. Core 2 Duo T7600 comes in at an unclear MSRP at unclear MSRP versus $138 MSRP, and it still gives you a 3.3% average FPS lead across 50 shared CPU game tests in our data. Core i3-2120 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 100.0% better value on paper (14.3 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1155.

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

Core i3-2120 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2006). That makes it the safer long-term bet.
