yeah, I saw a good 26 page review on Guru3d.com. Said it wasn't as good as expected, but the price is very reasonable for a card that sits somewhere in between Nvidias top offerings. And the price didn't get skewed in the conversion to Euros either.
Apparently they're noisy and not as good value as a current 8800 GTS. This might change with a small price drop.
Personally I would stick with Nvidia - however there's many personal reasons (i.e. what I use it for) rather than fanboy devotion.
I saw it a couple of months ago, supposedly, its a bit of a monster!
