Blu ray isnt really that worth it, just download high def movies and you are pretty much good.
670 is a lot better than 660 Ti and worth that extra cost.
don't look down on i5 3570k just because people say i7 3770k is better at video editing and stuff. While that is true i5s are still very great with video editing and a great way to save some money/spend it somewhere else.
Also that i7 deal is at in store only.
If you can buy it instore then get an i5 3570k+asrock extreme4 for around $300
and for the 670 http://pcpartpicker.com/part/asus-video-card-gtx670dc22...
this one would seem the best right now given its price and high stock speeds out of the box meaning if you don't want to Overclock your GPU this one is already overclocked for you and if you still want to Overclock this one can still be pushed quite a bit or you can get this one
