Crossfiring 2 HD 7770's

Last response: in Graphics & Displays

Hi I was wondering if i can crossfire a Hd7770 1gb(http://www.amazon.com/ASUS-HD7770-DC-1GD5-V2-Radeon-GDD...) with a 2gb version (http://www.amazon.com/GDDR5-technology-Graphics-Cards-H...)


Additional Info: I have a Sabertooth 990fx and the HD 7770 i have right now is a HD 7770 Dco 1gd5.
This is not the V2 like in the link. Does This matter?

Thanks for the help i know it was a long question.

You can, just know that if you throw in that 2 gig it's still going to run on 1 Gig of VRAM. The 7770 has a really low memory bus, which some people say will make it bad to crossfire, I don't crossfire anything so I can't tell you for sure. I love my 7770 as a single card though.
