I would either post to the Adobe Premiere Hardware Forum, or ask a MOD to move this thread there: http://forums.adobe.com/community/premiere/hardware_forum
While there are many forum subscribers, who hang out in both places, there are a few, who only spend time in the Hardware Forum, and a couple are the people, that I would want to see the question, to respond to it.
I can't answer for anyone else, but my best GUESS is that the 2600k (or 2700k) is used by people building with a very low budget... and those with more $$ go past the 3770k and on to the 3930k
Yes the 3930k would be ideal, however 2x the money.
How do I even post in the hardware forum? It doesn't seem to allow me.
Do I just message a one of the main guys to get moved, like Harm?
