Quick Answers

So, is E2-3800 better than Athlon II X2 245?

It depends on what you want from the system. For gaming, Athlon II X2 245 is ahead with 123.1% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, E2-3800 pulls ahead with 0.2% better PassMark.

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

For streaming, content creation, and heavier multitasking, E2-3800 is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 4 threads.

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

E2-3800 is still the much better call for a fresh build. E2-3800 comes in 51.5% more expensive on MSRP at $100 MSRP versus $66 MSRP, and it still gives you 0.2% better PassMark. Athlon II X2 245 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 51.2% better value on paper (17.2 vs 11.4 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM3.

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

E2-3800 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2009) and more multi-core headroom with 4 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.
