Quick Answers

So, is Core i3-2105 better than Athlon 64 X2 6000+?

Yes. Core i3-2105 is the better all-around CPU here. It gives you a 2.2% average FPS lead across 48 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?

For gaming, this matchup is basically a tie in the data we have.

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

For streaming, content creation, and heavier multitasking, Core i3-2105 is the stronger fit. You are getting 0.7% better PassMark, backed by 2 cores and 4 threads.

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

Core i3-2105 is the better buy right now. Core i3-2105 comes in $312 cheaper on MSRP at $138 MSRP versus $450 MSRP, and it still gives you a 2.2% average FPS lead across 48 shared CPU game tests in our data. It is also 228.2% better value on MSRP (13.3 vs 4.1 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i3-2105 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2007) and more multi-core headroom with 2 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
