Best system possible for 2200-2300 See builds listed and give me inpu

It’s a matter of best bang for the buck (see Builds below) I game maybe 7 hours a week the rest of my computer time is spent converting Videos of our children’s latest band, march riding dirt biking etc.. whatever, when I am working my computer is folding/SETI full time so good cooling is a must and I considering getting into mining bit coins but that will just be a hobby when I am bored and have beaten all the games I play which are EQ2, D3 and guys from working trying to get me into Eve (I game at 1920x1080)

If I get a single GTX 680 I can get a 3770K on Z77 MB 2x 120Gb SSD 16Gb of ram
If I get a 3570k I could get dual GTX 670 on Z77 MB 2x 120GB SSD 16 GB of tam
If I get an X79 3930K I would only get 8 GB for the motherboard and a single GTX 670 with the 2 x 120 GB SSD
I have a hard limit of 2500 and about 300 of that is ear marked for a new router and NAS box for backup.6 years ago we decided my yearly bonus/Tax return is to be considered free money it is our once a year splurge and we alternate who it goes to last year it was my wife and this year it is mind to spend on something foolish so it isn’t a matter of buy half now and the next half later this is my once a year spending spree no hold bars and I won’t do it again till Dec 2014 so I have to get a complete system with a monitor, and be able to last me three years.
