Quick Answers

So, is Pentium M 780 better than Celeron SU2300?

Yes. Pentium M 780 is the better all-around CPU here. It gives you 5.5% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Pentium M 780 has the edge because it leads the single-thread side of this matchup with 5.5% stronger overall PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium M 780 is the stronger fit. You are getting 5.5% better PassMark, backed by 1 cores and 1 threads.

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

Pentium M 780 is the easy recommendation for a fresh desktop build. Pentium M 780 comes in at an unclear MSRP at unclear MSRP versus $134 MSRP, and it still gives you 5.5% higher PassMark. Celeron SU2300 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games.

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

Celeron SU2300 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2009 vs 2005). That makes it the safer long-term bet.
