Unless you are able to sell 5830 to me $109 shipped immediately, then I think you should stfu. Availability has its value. Sapphire 5830 at $160 is still cheaper than the cheapest Sapphire 6870 (rebate can only be used once per address, even with rebate it is $190). If you are building multiple machines with 4 x GPU, the price difference add up to a lot of money very quick.
Sure $109 price point is great, IF you can get them. Otherwise you'd have to wait god knows how long, and be god knows how fast to get any at $109.
Maybe you should learn how to browse newegg before you tell other people to stfu. There's multiple 6870 models available for $165-$175 after rebate and a Sapphire one for $175 w/o rebate. At those prices the 6870 is certainly a better deal than the 5830 for $160.
