I received my Sapphire 3870 Wed and have been playing with it and after running 3dMark06 my score to me seems very lacking. Attached is my score with CPU-Z and GPU-Z running. Also I notice GPU-Z states cf is disabled even though in CCC Enable CrossfireX is checked.

it's not enabled, the lowest I get with 2 hd3870's 14993 so something is not right

Your processor is holding you back, is my guess.

its the amd cpu.. my 6000+ at 3.350 gig scored 13000 in 2006 crossfire and 11000 with just one 3870 card.. at its default resolution the 2006 is cpu limited..

crank up the resolution and bung in some AA and u will see some nice gains with two cards.. at the default resolution u wont..

dont be mislead by intel users saying something is wrong they get more.. nothing is wrong.. except perhaps the amd cpu where default 2006 scores are concerned..

still it makes a change from why is my phenom score so low..
