After much research and deliberation I decided to go with the EVGA GeForce GTX 670 FTW+ 4GB w/Backplate over the 680 with 2GB.
Figure that the 670 has plenty of power and being a PCI-E 3.0 card with 4GB VRAM offers a measure of future-proofing as well.
I was interested in the ASUS offerings but cost and availability were concerns.
Card has been ordered
now for the hard part… waiting for delivery.
Thanks for the input!!!
