I would rate it a 4 because of the graphics card and CPU. The 550Ti is a horrible graphics card. It isn't a good graphics card for gaming at all. I would not recommend any card lower than the gtx 560Ti if you're going with Intel. The CPU is also not the best, it's very power hungry for the performance it gives. Finally, the power supply may not be the most reliable, although I'm not sure since I've never heard of the PSU before.
If you have $1100, I recommend going with the Intel i5 2500k and at least the gtx 560Ti.
The AMD FX series has been a pretty large disappointment, and there's not much to look forward to in the immediate future. Some of the part selections such as case and psu are brands that wouldn't necessarily be trusted. Give something like this a shot:
