Having sited a brand new Sapphire 5850 for £138 (not a bad price considering I bought my first for £207 two years ago) I decided to enter the world of crossfire for a cheap upgrade. I had to swap the position of my original card to keep good air flow because of the different position of the GPU cooler fans, interestingly with my mild overclock (Any higher I become aware of the extra fan noise which I do not like) temps have dropped 5 degrees compared to single card. Just done my first bench mark in 3D Mark 11; so far so go, not quite sure of the scoring are these results any good?
