Good replacement for MacBook Pro 15.4" Retina?

I was thinking of this:

Tell me if I got the budget wrong and the reason I got an expensive MoBo is because I want a 9590 or 9570 and that needs a good Digi VRM. 750 watts is overkill but allows me to add a 9000 series CPU, a thick radiator watercooling solution, another/more power consuming GPU and more RAM. I put a PS3 in as I want to play with friends and my dad is subscribed to LoveFilm - Red Dead Redemption is also on PS3.

Idea's?

You will want to get an aftermarket cooler with the 9590 or 9570. A SSD could be and upgrade later on.

I think I said that where I listed possible future upgrades.

Sorry didn't see that.
