Uh, no.
They're incredibly overpriced at retail stores and usually only sell boring brands, and mid-range cards. The highest you'll probably find in a retail store is like a 460.
Since you have an endless budget I'd buy two of these (which are $520 each).

I used to find 8800GTX's in retail stores when they were new... haven't checked lately though.
