Quote - could it be ram related?  I only have 8 gigs of ram in this box.. have another 8 otw tho

I doubt it. I've only got 12gb, but running at 2ghz. For a test scene like a single figure in IBL, 8gb is comparatively overkill. ;-)

I'm trying out Luxmark, but its only picking up 4 of the 384 GPU cores between the two cards for some reason. I'll have to fiddle with it a bit I suppose! 

Edit: found the benchmark part. Running a cpu-only.
