This will sound bad! But spend as much as you can afford! Your setups look very good, although I wouild change the ram in that last one to Corsair XMS3 or something, had dead sets from ocz before (then got upgraded to xms3 for free

).
I like the i7 build more, and would future proof you for the next few years. I would also change the hard drive to a WD black. Other than that it looks wicked and you wont regret it. I wouldn't buy an SSD now, wait for a bit longer for the prices to become a little more reasonable (rumoured this year)
