Yes. Core Duo T2400 is the better all-around CPU here. It gives you a 1.6% average FPS lead across 50 shared CPU game tests in our data and 0.1% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core Duo T2400 is the better pick. According to our tests, it delivers 1.6% 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 Duo T2400 is the stronger fit. You are getting 0.1% better PassMark, backed by 2 cores and 2 threads.

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

Core Duo T2400 is the easy recommendation for a fresh desktop build. Core Duo T2400 comes in 119.4% more expensive on MSRP at $294 MSRP versus $134 MSRP, and it still gives you a 1.6% average FPS lead across 50 shared CPU game tests in our data. Pentium 987 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 1.6% in the shared gaming data.

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

Pentium 987 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2006). That makes it the safer long-term bet.
