That build on Cybertronpc is not really worth $570 in my opinion. If you could piece together your own PC with individual parts you can probably get something significantly more powerful. Then again that's the price you pay for not knowing how to do so.
If are still set on buying from Cybertronpc I have to say they don't have a wide selection of parts to choose from. They don't specify the brand of the ram, hard drives and graphics cards so you might get crappy ones. Also they still offer the old GTX 550 Ti and the HD 7850 is weaker than the GTX 660 but costs more?
The HD 6670 will fare better than the GT 610 and they don't appear to offer SSDs so if you want one you'll have to buy it separately. A 128GB SSD can easily be found for...
