SLIing xfx 8600gt... how better is it going to get?

[pslee]

I would like to ask you how good it is going to get. I would like to play world in conflict when it comes out. now when i run 3dmark06 cpu score is about 2480 and video card score is about 2410/2100, which gives me composite of 5750. If I get one more card how better will it get?

world in conflict will play well on just one card, my friend has a 1900 and the wic beta demo and it looks great
