Guy, i found an refurbished unit X1 carbon G4, with i7-6600u, 8GB ram, wondering able to upgrade the Ram? i was trying to search online for comparison of this i7-6600 with i5 8th gen processor but cont find.
Does latest i5 processor will perform better than older gen i7? because want to see if add more a bit money for newer laptop but dont want to spend too much money for latest i7 so just compare with i5 latest gen..
