New OS for old Vostro 1400

I want to put Windows 10 on my Vostro 1400, after I replace the hard drive I see Windows 10 disc on Amazon for $around $60. Is that a good idea? I also see XP Pro (Is that obsolete) for around $10. Everything I need seems to work with my current Vista OS, but the hardrive is bad so I wouldn’t mind a little upgrade, without spending much. It’s an old computer.

Thanks,

Robert
