Looking at a very similar build but going with an nVidia card because I want to get good performance with video editing in Premiere as well as LR and PS and Premiere doesn't play as nice with AMD video cards. Just pulled the trigger tonight on a new Dell U2713h wide-gamut monitor. Still trying to decide between nVidia GTX 680, Titan, or Quadro k5000 ... most likely going with the 680. Couple of SSDs for OS, apps, and scratch/cache files anda couple of terabytes conventional drives for data storage. Now trying to decide on a case, power supply, and cooling options as audio recording and editing is also a priority and so as near silent operation as possible is a must. What are your thoughts on that?
Yes, for video editing with Premiere, nVidia is the way to go, and I don't think you can go wrong with the GTX 680.
As for power supply, something from Seasonic, with the 680 I would go with at least 750 watts.
With a X79 MB I would go with a Full Tower case. I've looked at the following cases, but I'm still on the fence as to which one.
Rosewill THOR V2-White Edition, THOR V2-W Gaming ATX Full Tower Computer Case, support up to E-ATX / XL-ATX, come with Four Fans
COOLER MASTER HAF X RC-942-KKN1 Black Steel/ Plastic ATX Full Tower Computer Case
Cooler Master HAF 932 Advanced Full Tower Case with SuperSpeed USB 3.0 (RC-932-KKN5-GP)
The Core i7 3930 doesn't come with a heat sink, if you want something silent, go with liquid cooling, $100 will get you something good, and will easily fit inside one of the case's listed above.
