PC Specs - Should I be concerned?

I, in a total lapse of thoughtfulness, didn't even think to check the system requirements of Defiance prior to pre-order.

The stats you listed should be fine. I'm using an old EVGA 680i motherboard with a Q6600 and a pair of GTX 465's and it ran fine in the Betas. Depending on where I was at any given time, I can run it on high and still get anywhere from 28-50 FPS, unless I'm in a heavily populated Arkfall, where it'll drop to the teens at times.

I could get better FPS on medium I imagine, I just didn't try it to see what the numbers would be.

You might tone it down a little on the graphics so arkfalls won't bog you down, but what you have is just fine.

I was able to play defiance on my Surface pro with a little choppiness now and then. Think you'll be fine.

Geez! That's insanely powerful.

And you shouldn't have any issues with the Q6600. That was my old CPU before I recently built my new rig, the Q6600 never had any bottlenecks for gaming, it was all the graphics card + ventilation (mine was poor ventilated and dusty).

The beta ran with flying colours on my 4 gb, 5770 and Q6600, doubt you'll have any trouble.
I doubt I'll have any issues running the full game.
