Yes thanks. I think its best to go for game console as I cant really help him with a pc, so Ill buy him a stardard pc in a gew years when he understands it better and he can upgrade himself. Anyway I cant find any answers as to why a pc will be better for gameplay.My 2 cents worth...seeing that your son is 11
Just get an XBOX One or PS4 or wait for the new versions coming out in next couple months.
No need to worry about him crashing windows first of all, No need to worry about viruses, It will do everything he wants plus more like movie streaming ect. like netflix which you can then use on the TV when he is not playing. You wont require upgrades when new games come out and should be fine for atleast the next 3 or 4 years if not longer. The graphics is awesome as well.
So for someone that isnt too technical referencing the whatsapp, i would say this is the best and easiest option as well as cheapest.
I have seen second hand Xbox one 1terabyte i think for around R4k
I think I will go the playstation route as we allready have a ps3 and he know the system. And as far as I have read on google it seems playstation is best, they say ps4 have sold something like 100mil.
