Buy this or wait?

Finally got the money for my planned build. Recent talk of new motherboards has made me waver a bit though.... would it be worth waiting to see what new chipsets come out? Could they make much difference to system performance on gaming and video converting? Here's my planned system:

ASUS P5WDH Deluxe;
E6600 C2D;
2 x 1Gb Mushkin PC6400 4-4-3-10;
150 Gb Raptor

Already got a 7800GT I'm gonna use until DX10 cards come out.

Planning on overclocking to 3.0GHz with stock HS/F.

Any help would be appreciated.

Thanks for the help and thanks for the car thing..... no longer will I be seemingly preoccupied at odd times....
