help with version of lubuntu

[Maurice Strik]

Hi,
I have a AMD Athlon 64 3200+  2 GHz from the year 2006. This was delivered with windows xp but because xp support will stop next year i'm looking for an alternative because the desktop is still very good and i don't want to buy a new one. I think ubuntu (lubuntu) is a good alternative for me, but i'm not familiar with ubuntu so i don't know which version i should take (lubuntu)

Can someone help me?

Kind regards,
Maurice
