OK so I have built my pc and its running on onboard graphics atm and am now about to purchase a 7850 , I did contemplate the 560 ti superclocked but I think this card will go nicely , all my other specs are above par but just incase people would like to know, asus p8 z77 mobo , intel i5 3570k cpu , 8gb corsair vengeance RAM , 600watt psu.

Now I sw the asus 7850 for $420 so i have saved and can now afford that , bu then i came across the sapphire version of the card for about $360.

So my question is , what am I losing/gaining by purchasing one card over the other

cheers and thanks if you can help me out :)
