That's awesome, I love hearing stories like this. I was lucky to have access to a PC since I was about 8 years old and computer literacy is probably the most useful skill I have. Nothing teaches PC literacy better than pirating software with complex readmes lol or having to fix the family computer because you infected it with a virus. Had me stressing, looking at the task manager and searching for the origins of every .exe to find the culprit

I probably wouldn't let my son install a GPU until he's a bit older just because of the cost lol but it is simple enough for a teenager to do, I think.
