Quick Answers

So, is Pentium 977 better than Core 2 Duo E7500?

It depends on what you want from the system. For gaming, Pentium 977 is ahead with a 2.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Duo E7500 pulls ahead with 0.8% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core 2 Duo E7500 is the stronger fit. You are getting 0.8% better PassMark, backed by 2 cores and 2 threads.

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

Pentium 977 is still the much better call for a fresh build. Pentium 977 comes in 18.6% more expensive on MSRP at $134 MSRP versus $113 MSRP, and it still gives you a 2.1% average FPS lead across 50 shared CPU game tests in our data. Core 2 Duo E7500 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 19.5% better value on paper (10.2 vs 8.6 PassMark/$), 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?

Pentium 977 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2009). That makes it the safer long-term bet.
