I've been thinking about possibly upgrading my mobo for dual 16x crossfire and sata 6GB capability. So out of curiosity I downloaded GPU-z the other day to see what my crossfire cards were running at. According to GPU-z my cards are running at 8x and 4x, not the dual 8x that my board is supposed to be capable of. Is there any reason for this? Can I change it or is GPU-z wrong?
My mobo is an Asus M2A78T-E and i'm using 2x Sapphire Vapor-X 6870's
