Skreedles :
That isn't the classic version.
The closest I have heard of a "Classic" version is the EVGA Classified. MSI has no such thing now or in the past.
The have two versions of the 970 none of which are "Classic" :

Tho 4 have been announced
MSI GTX 970 Gaming 1140 MHz 1753 MHz Boost Clock: 1279 MHz, 10.6 inches
MSI GTX 970 Gaming LE 1076 MHz 1753 MHz Boost Clock: 1216 MHz, 10.6 inches
MSI GTX 970 OC 1102 MHz 1753 MHz Boost Clock: 1241 MHz, 10.83 inches
MSI GTX 970 OCV1 1076 MHz 1753 MHz Boost Clock: 1216 MHz
I don't think we will ever no much about the others.... with just a $10 difference and longer length I can't see there being significant interest and as a result I don't think many sites will look to review them .... other than buying one and testing it, there's no real source of information.
