You could probably buy the components and build the same spec system yourself for about $1000 USD. Also unless that CPU is the 'k' version your really limiting your system on over-clock potential. The GPU is also the non-TI version by the looks of it which lacks in performance.
It's not a "bad" build, but i certainly wouldn't pay almost $1600 USD
The above number does not include shipping or tax. You decide from there if you think not having to put it together yourself is worth the difference. Remember, this is based on that exact specs you listed. There are likely other options that might be better for that money such as going for a stronger video card, processor, etc.
