Help me build my first mining rig please.

GPU mining Bitcoin window is closing now, either wait for ASICs to come into the game around October or try GPU mining Litecoins and either keep them or sell for BTC.

Problem is even if I order now I will not get them even close to October so that ship has sailed also.
I just want to get in now

I bought a 5770 7 weeks ago that paid for itself in 6weeks(not counting electricity), I just sold it because I'm moving xcountry so ended up with a 100% return on investment.  Your numbers are good I believe, and 5xxx cards are a good choice so go for it. 
disclaimer: I started mining just as the price started spiking and my pool had a long streak of good luck so don't expect as large of a return as I had.
