Quick Answers

So, is Pentium E5700 better than Core 2 Extreme X9000?

It depends on what you want from the system. For gaming, Pentium E5700 is ahead with a 1.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Extreme X9000 pulls ahead with 1.1% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core 2 Extreme X9000 is the stronger fit. You are getting 1.1% better PassMark, backed by 2 cores and 2 threads.

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

Pentium E5700 is the better buy right now. Pentium E5700 comes in at an unclear MSRP at $75 MSRP versus unclear MSRP, and it still gives you a 1.7% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core 2 Extreme X9000 is still stronger for heavier multi-core work with 1.1% better PassMark. It is also 100.0% better value on MSRP (14.6 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium E5700 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2008). That makes it the safer long-term bet.
