I'm building a new system, Will do some gaming,
CPU will be a i5 3570K,
Mobo Asrock Z77 Extreme 6
I'm looking at a GTX 670 or 660.
The cost diff is about $120. Both of the cards will be light years over what I have now. I've read nVidia's specs on the two cards but w/o any experience with them not sure if the difference is worth the extra cost.
