Bitminer PC build question

Hello everyone on Tek Syndicate. I am wondering if it would be worth it to buy an amd crossfire build to mine bitcoins and what GPU's that would be smart to buy. Idgaf about the power bills, I live with my parents (15 years old). Will it take too much time to actually get enough bitcoin for it to be worth it? I don't have a very strict budget, so unless it is around a 1000 bucks, i would do it. (Of course if it doesnt take ages to mine bitcoins with such a build).
I'll put the question on INBOX.EXE because I recon it would be a question worth for razetheworld as well. 

I would love to a see a response to this as well.
