Quick Answers

So, is FX-8120 better than Core i7-970?

Yes. FX-8120 is the better all-around CPU here. It gives you a 2.4% average FPS lead across 50 shared CPU game tests in our data, 0.7% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, FX-8120 is the better pick. According to our tests, it delivers 2.4% 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, FX-8120 is the stronger fit. You are getting 0.7% better PassMark, backed by 8 cores and 8 threads.

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

FX-8120 is the better buy right now. FX-8120 comes in $878 cheaper on MSRP at $205 MSRP versus $1,083 MSRP, and it still gives you a 2.4% average FPS lead across 50 shared CPU game tests in our data. It is also 432.1% better value on MSRP (32.2 vs 6.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

FX-8120 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2010) and more multi-core headroom with 8 cores / 8 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
