Which one is better for gaming?

If gaming is the priority, Athlon II X3 450 is the better pick. According to our tests, it delivers 0.7% 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, Athlon II X3 450 is the stronger fit. You are getting 78.2% better Geekbench multi-core, backed by 3 cores and 3 threads.

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

Athlon II X3 450 is the better buy right now. Athlon II X3 450 comes in at an unclear MSRP at $87 MSRP versus unclear MSRP, and it still gives you a 0.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (21.4 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Athlon II X3 450 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2006) and more multi-core headroom with 3 cores / 3 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
