I was lucky enough to stumble upon $309 (including shipping) DIAMOND 5850's on Amazon.com.
Two actually. I immediately clicked add both to cart but by the time I finished checkout, one had sold.
I was bummed, wanting 2 of the SAME designer cards. I dont like nor wanted a HIS 5850 for $315 + shipping on newegg, but that was all they sold all day.
Then when I went to buy the HIS, I stumbled upon a DIAMOND for only $305, and got it for $317 with shipping.
I'm happy. Although I dislike ATI, Nvidia's greedy prices and inability to release the 300 series on time really gave me no other choice. I love Nvidia more, and dislike ATI, but ATI gets my business bc they're just plain better at... business. Even if their drivers and programmers suck.
