Quick Answers

So, is Core 2 Duo T5600 better than Core i3-540?

Yes. Core 2 Duo T5600 is the better all-around CPU here. It gives you a 1.9% average FPS lead across 48 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 Duo T5600 is the better pick. According to our tests, it delivers 1.9% more average FPS across 48 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 T5600 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 Duo T5600 is still the much better call for a fresh build. Core 2 Duo T5600 comes in 81.2% more expensive on MSRP at $241 MSRP versus $133 MSRP, and it still gives you a 1.9% average FPS lead across 48 shared CPU game tests in our data. Core i3-540 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 80.5% better value on paper (11.7 vs 6.5 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1156.

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

Core i3-540 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2006). That makes it the safer long-term bet.
