I can't recommend any of those:
http://cpuboss.com/cpus/Intel-Core2-Duo-T5600-vs-Intel-Celeron-N2840
The Celeron is apparently a tiny bit faster than that AMD cpu, but it's still slower than my 8 (!) years old notebook cpu(Intel Core 2 Duo T5600 1.8 Ghz). Simply put, with both cpus, the main activity on that computer(notebook?) will be waiting, especially if paired with a HDD.
Well, those cpus have one advantage over my old cpu: Lower power consumption. Battery times should be good, if the battery is not sized down as well.
Also, if there's going to be Windows 7 or later on that machine, keep in mind that you need 4 GB RAM. The 2 GB minimum requirement of Win 7+ is a mean joke, it performs horrible with just 2 GB.
