Finally, after alot of research, many questions and few nights without sleep. I finally made my choice !
Two Galaxy 670 in SLI. 300$ each, I couldn't resist.
After many consideration the AMDs card are little more powerful on some aspects but I play primarly nVidia optimized games and second I would like to install Mac OS X as a dual boot wich required a nVidia card (Final Cut Pro is just awsome for movie editing).
But I really appreciated you help guys!Edited by The Islander - 2/16/13 at 8:01am
