HD6850 crossfire query

I'm planning to add another Hd6850 along with a TX750 v2.
But i have some questions regarding my upgrade.

1.My mobo Asus m4a785td v evo has two pci-e slot x16 & x4, so if i add another,will i be getting a performance boost or it will be crippled by the x4 lane.

2.Should i wait for the prices of hd6000 series cards to fall or just go ahead with the upgrade(planning to buy before christmas).

3.I'm also planning to oc both the cpu & gpu.
Will the tx750v2 be enough to power the whole system.

Crossfire users please advise.

Its 4% to 10% lesser than X16-X16 setting in the most demanding games. Up to 1080P, the difference is around 2% to 6%.
