Hi
No! Sorry but Mac's don't work well at all with XP, especially 11. Cooling is a BIG issue with Mac's. Mac's are used for business/daily work, even some editing but definitely not gaming! As for your CPU, even if you turbo boost it, the experience will be bad. You could have gotten a high performance laptop even with a 1080 or 1070 GPU for around the same price. That would have been great and gotten you a high quality experience. I would suggest returning the Mac and get a gaming laptop but at the end of the day, it's your choice.
Cheers,
Rishi
