Budget Gaming PC/Laptop for The Sims 4

Hi all, looking to surprise my girlfriend with a new PC or gaming laptop for Christmas but I really need help!
Basically she just wants to be able to play The Sims 4 smoothly. She's currently on a Mac and she complains about it a lot.
Problem is my budget is pretty low, have only about $750 - is this going to be doable or should I forget about it? Any pointers would be much appreciated!
