Wait a minute, I've found one under $300.
Here it is: http://www.newegg.com/Product/Product.aspx?Item=N82E16814202030 (better)
and
http://www.newegg.com/Product/Product.aspx?Item=N82E16814131478 (should be 2nd priority)
If they have the same processor in their stock, you are going to receive the same processor. Otherwise an auto-upgradation.
You can understand what happened only after receiving it.
