It really depends when you bought it.
I'd give it 7 or 8 as well for several reasons.
As rolli said, an HD 5850 would have balanced it out a lot more, and for a gaming computer, an i5 750 will perform just as well if not better than an i7 920. As for the RAM, I would have bought G.SKILL PI series with CL7 latencies and better heatsinks for less money, and the cooler's not too good with handling i7s, a Meghalems or Thermalright Venomous-X would be a better choice.
I do like the SSD for boot drive, and the case. The PSU could also handle HD 5770 CFX.
In terms of cost, I would roughly guess $1,200 or so in USD?
