A good list of parts, but I have a few suggestions.
For editing the 2600 with hyperthreading is appropriate. But, why not buy the 2600K instead? The extra $25 will give you the capability of raising the default multiplier from 34 to the 40-45 range, giving you considerably more compute power.
You need not oc immediately, but I think it would pay to preserve that option.
Supposedly in April, the (22nd?) ivy bridge is supposed to launch. If your build time frame is that flexible, it may pay you to wait. For the wait, you will see a 10% improvement in performance and probably better overclocking. The 3770K is a 3.5 base ghz chip which will be priced similarly to the 2600K.
For graphics, I think the GTX560ti or similar is appropriate.
But, it only needs a good 500w psu. The newer 28nm graphics cards will be more power efficient. The 7970 needs the same 500w psu, and I think the upcoming GTX680 will need the same. If you ever want to upgrade graphics, just replace the GTX560ti with a stronger card. No need for cf/sli and extra power.
I suggest you back off on the 950w unit, and look for a quality 650w unit.
Look at Seasonic, PC P&C, XFX, Corsair, or Antec for a quality unit.
For a similar price, in the 120gb range, I might go with a samsung 830 SSD, or, the Intel 520 unit which is a tad higher, but comes with a 5 year warranty.
Both are considered to be the best for reliability and trouble free operation.
