Two Revisions
Just recently, GIGABYTE has released a revision 2.0 of this video card. We have the original revision 1.0 on our test-bench today, sent by GIGABYTE prior to the launch of the GeForce GTX 760. Since the launch, GIGABYTE has updated the video card to a revision 2.0 update. Note that both revisions have the exact same specifications, clock speeds, and sell for the exact same price of $259.
Revision 1.0, on the top, is printed on a lighter blue colored PCB, and has a smoother, rounder, and glossier WindForce 3X cooler housing. The revision 2.0 version on the bottom is printed on black PCB and has a less glossy fan housing. The housing is also not as smooth or rounded. We reached out to GIGABYTE for answers, and GIGABYTE's response is thus:
The only difference between them is the fan cover. Rev1.0 is plastic and Rev2.0 is metal. They both have the same exact spec. The Rev1.0 will phase out soon.
So literally the only difference is in the fan cover, one being plastic, the other metal. Therefore revision 1.0 will reflect the performance and overclocking potential of revision 2.0. As you will find out, that overclocking potential is very good.
