Quick Answers

So, is Core i5-655K better than Celeron M 560?
Yes. Core i5-655K is the better all-around CPU here. It gives you a 1.0% average FPS lead across 50 shared CPU game tests in our data, 0.4% 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, Core i5-655K is the better pick. According to our tests, it delivers 1.0% 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, Core i5-655K is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-655K is still the much better call for a fresh build. Core i5-655K comes in 151.2% more expensive on MSRP at $216 MSRP versus $86 MSRP, and it still gives you a 1.0% average FPS lead across 50 shared CPU game tests in our data. Celeron M 560 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 150.0% better value on paper (23.3 vs 9.3 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA478.
Which one is more future-proof for 2026 and beyond?
Core i5-655K makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2008) and more multi-core headroom with 2 cores / 4 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
