Thanks for the answers, everywhere I went said the same thing that Vram is separate. The computer I am using now has 6 GB's of DDR2 and was using a 9800GT until a fan stopped working and fried it so I replaced it about 7 months ago, now I think everything is slowly failing so I have ordered everything to build a new one.
The 6670HD is better than my old 9800GT which ran Crysis on medium to high settings. This one runs it on High. So I figured 12 GB's of DDR3 and a quad core processor (instead this old core 2 duo) would make all the difference in the world
My only question is now, why would my new motherboard support up to 64 GB's of ram if you can't use it? Most program don't need more than 4, about the only thing that does is games. That is why I was wondering if I could dedicate more ram to the graphics card.
