Help Low 3dMark

[Lolcb]

Well basically after I installed watercooling blocks etc to my setup, I notice a huge drop on my 3dmark.

My specs:
X6800 C2d
8800GTX SLi
2GB Cellshock
680i ECS motherboard

So I used to get 13.5k score for 3dmark, now im only getting 5k in 3dmark?? Anyone have any idea?

I tried using driver 158.22 and 97.92 and 3dmark wont detect SLi.

You can use CPU-Z to check right?

Or is there any other program to check?

Assuming my pci-e slot is running 1x or 8x

How do I go about changing it to 16x?
