Why do they give away $11.000 computer?

Hi, this morning I had to update my amd drivers, and I saw that they were giving away some really expensive product like $11.000 computer and I wondered why ? (link for more info). I know that this kind of contest have generally some loopholes or benefits for them, but right now I don't see it.

I know they only want to give 2 computer and 10 ssd, but why do they want to make this won by luck?

What do they want to achieve with that?

If someone knows tell me

You're obviously affiliated with them in some way, this is either a desperate plug or some sort of scam. Your name is even in the link

well I signed up because the only thing they asked me was an email account and my adress, and none of these are a secret and could lead to me being robbed (it is not like they wanted my credit card number or money in any way), and this link was supposed to redirect to this. (To be honest, they gave this link in the confirmation email, in order to be shared on social networks, so that I'd someone sign up after this link, I'd win too if they win or something like that, because after thoroughly reading their terms, it seemed like I could lose 2min to enter since it wasn't demanding anything weird)

However, I don't see it being a scam since it was Amd advertising it in their update utility, as they usually do advertise their latest graphic cards or such. It just is a marketing thing, I just don't get it that's why I asked!

sorry if it looks like a scam, I'm "affiliated" because I have an Amd graphic card and it is because of that that I heard about this. (Furthermore I didn't ask anybody to sign in, just to enlighten me about why they would want to do that)
