Here in belgium they are available at the same price. Which would you for? I'm opting for the rampage because of the sound card and ROG feautures. And I don't see the point of usb 3 or sata 3 as I can just buy a pci card.

I'd go for the Rampage II Extreme as well, simply because if they're the same price the R2E is a better deal. I don't mind missing on SATA III and USB 3.0, like you I suppose I could just buy a controller card later on.
