Difference between sapphire 6870s

[perfecxion]

New egg has at least 3 different 6870s and im wondering what the difference is because one is 175 and the other two are 200.

Im trying to stay in the 160$ range so im deciding between the msi hawk n460gtx (168 shipped after 10 newegg coupon) vs the sapphire 6870 3l, not the flex or vapor (165 after new egg coupon). ill be running the card at 1920x1200
thanks

From what I see the two $199.99 cards have AMD Eyefinity and physics processing support. The $174.99 one does not show this.
