Don't buy it. I was going to buy two, however, after doing some talking with Sapphire I found out that the Atomic 3870 is a "limited" run and only 300 have been made (50 for sale in U.S). And only 300 will ever be made. They are getting ready for the 3870X2. The Atomic is not worth the price and I suggest you move onto the 3870X2 (as I have).
Oh, and Sapphire has given exclusive rights to NewEgg to sell the Atomic 3870. Thus, only NewEgg will sell the stock in the U.S.
