Your best guess is currently correct from any price searching I have done. There simple isn't any GTO competion in that price range. I'd ask what games you play as that can sway whether you go green or red. But at those prices it just doesn't matter. The 6800GS supply is drying up and $195 shipped is about as good as you can find. Eitherway those two trade blows with the GTO coming out on top IMO.
If you can find a stray X850pro or X800XL for that price, then those would be better. Otherwise if that price range is firm, the GTO is your card.
