I'm not real familiar with US sites that sell prebuilt machines, so from the little research I've done the PC there seems good for the price actually. Building it yourself would give you a better machine for the price, but if that's not an option then you may as well go for that really.
I didn't see the SSD listed in your initial post hence part of my disapproval really, a $1000+ build without an SSD is inexcusable IMO.
I do think the PC isn't fantastically specced as, like I said above, a Z77/4770 system would give you much better bang for your buck, better CPU performance, and probably allow you to get a GTX 760 or maybe a 7950, something along those lines, but I can't seem to find anything decent with that combo for a similar price.
