Turns out I do have a faulty HD3870 card, waiting for a replacement so got a HD3870x2 loaner which runs OK on the P5W DH Dlx, seems to lose out very very slightly to 2 x HD3870 though.
Looks like GDDR4 at work here.
X2 uses 1.0ns GDDR3 memory and clocked and usually clocked at 825MHz
3870 uses .08ns GDDR4 memory and clocked at 777MHz
See the difference now?
