well first off.. it would be great to know the rest of your system...
second.. I don't think you should lock your choice to one manufacturer, there are many great options from other manufacturers.
I guess if you want the cream of the crop.. you would be looking at an EVGA SC2 1080ti Founders edition.
if not, then I would suggest getting an ASUS 1080ti STRIX, it's quite good.
a non set budget will buy you whichever you like the most.. check some reviews and make a decision like that (i think that would work best for you)
