Re: What would you do..........
I would spend about $55,000 on a new PC (w/ custom liquid nitrogen cooling) to go with the best 1080p HD plasma screen TV or which ever is the best.
Top of the line Mercedes AMG and modify the crap out of it (800+ whp). A pretty nice house with a full home theater, indoor pool, and the works.
I would have my own personal chef and housekeeper.
Even after all that, I still have way too much money. I think I'll dedicate a building in my own name to some organization. Mark my legacy.
Then I'll give a dollar to my sister.
Invest the rest.
