You will NOT bottleneck
You have no worries.
Also, there is no knowing of what things will go on sale on Black Friday, however, from past experience, I will
say that newegg usually has a massive component sale on Black Friday
With that said, I would definitely stay up late on Thanksgiving to keep an eye out for deals
On a side note, I would recommend the Radeon HD7950 over the GTX660 Ti. The castrated memory bandwidth will cripple it in the future. I personally would not want to take this risk - http://www.tomshardware.com/reviews/geforce-gtx-660-ti-memory-bandwidth-anti-aliasing,3283-11.html
