No gaming, pure video editing.
When mentioning "Basic editing" and "cs6" im thinking you plan on using premiere/aftereffects/encore...
if correct CS6 (as a whole) is neutral to video card brands, but "cuda based" encoding benefits greatly from nvidia cards.
Then again, with that power supply, you may want to look at budget (very low entry level)
600 series cards .... (ie GeForce GT 610, which also accommodates nicely on micro towers)
