I finally ordered my GX2 earlier today.
I had purchased a 3870X2 but it arrived damaged so I sent it back. By the time everything settled and my account had been credited the 9800GX2's were released. After reading reviews on the GX2 and seeing some comparisons involving COD4 & WiC I'm glad my 3870X2 was damaged.

I definitely liked my OC'd 8800GTX, it performed rather well @ 1920x1200. My 2 OC'd 1GB 2900XT's were okay but nothing special, there were no magic drivers as some suggested. Now, if these GX2's are the beasts that I believe them to be, I will be happy once again.
