Sempron 150 cannot be compared to i3, i5, i7, as it's a single core one.

(Money saver tips: leave out that expensive OS, go for Ubuntu. You won't be needing 4GB as well then, 2GB will do fine, however, it will probably make the machine harder to use for them, as it's so different from MS windows stuff... and they will probably not be familiar with it, and then have to change all the time.
I'm starting to blabber now, please ignore...)
