You ordered a HIS?
Yeah, it looks like all the 2nd tier vendors are using essentially the same cooler, Diamond, powercolor, HIS. Obviously it's not the best, but $30-$40 is a decent bit of coin on a $250 card. I figure that if I'm conservative with my OC (probably limiting myself to 1050-1150 without any overvolting) the cooler should be good enough.
I only found one review for the HIS card, but it seems relatively positive.
http://blog.testfreaks.com/review/review-of-his-radeon-hd-7850-2gb-pcie-video-card/ they hit 1.1ghz w/o voltage adjustment, and a 72* max temp, and remarked that the card seemed quite quiet at those temps. At $220 (after MIR) it's 15% cheaper than the DC2, and I figure at most I'm giving up 18% performance (1.1 ghz instead of 1.3) so yeah, it sounds reasonable. I'm also probably going to be CPU limited in most games, so squeezing every last bit of OC isn't a high priority for me, but there's too big a gap between the 7850 and the 7770. I didn't want to pick up a 40nm card because I only have a Corsair VX450, and in NYC I pay about $0.22/kwh
