6800 GT vs 6800 ultra for SLI and Single card

[Foghornleghorn]

I am going to build a monster soon and need to find a review for dual nvidia 6800 GT vs dual nvidia 6800 ultra and throw in a comparison vs a single card solution for the ultra. Basically I want to know wether I should buy 2 ultras or 2 GT's. Any help would be very appreciated.

New Computer may be:
AMD FX-55
ASUS A8N SLI
2 gig DDR400
2 SATA Drives(Not sure if I am going to RAID 2 Raptors)
2 GeForce 6800 GT's or Ultras
Dual Layer DVD burner (Still researching)
Soundblaster Audigy2 ZS Platinum
PCI Xpress compatible power supply (researching)
Watercooled by Koolance (CPU,GPU's,Nforce4,Hard Drives)

The Ultras would give better FPS but you wont notice the difference between SLI GT or SLI ultra. A pair of 6600gts are godlike enough.

The only review I did see was a pair of 6600's and they were the equivalent of 1 6800 GT. They also did a dual 6800 GT but didn't compare it to 1 ultra or 2 ultras.
