i know they offer great performance boosts and ive witnessed the power. it is awesome! but first ill get a solid build and add too it. i dont want to reduce my wattage because i want to xfire in about a year. i reckon 5870s will still be great cards by then. had a look at the UD3R but the feature set of the Asus is what draws me and it looks like a great overclocker for noobs with automatic BIOS reset and things like that. almost on par with the R2E which is a plus. patriot viper wont fit under the Noctua NH-D14 unfortunately. 

+1The 930 has one more clock ratio. And that's it.
