When I said good speakers, I wasn't talking about watts, noise or the amount of speakers, but about sound quality. (now thats something you can spend alot of money on

) If you find that a set of pc speakers that cost 100 bucks sound awesome, forget what I said. It saves you alot of cash to not get into this stuff. Ok, enough about that
Every time a new generation of gpus comes, you can get the same performance that the last generation offered for much less. There is no way that you will save money by buying 3x680s now. If you want get 2 680s go for it, but just know that its no money saving option. Like others have said, get a great cpu and mb, then a gpu solution that will satify you now and upgrade it whenever needed. If one 680 is enough for you now, nothing is stopping you from buying the second later (for a cheaper price).
Btw just because ssds aren't mechanical doesn't mean that they can't fail on you.
All i can say is that please listen to b negative. He knows what he is talking about and you will be better off listening to him. (in both storage and psu advice)
