Which 780 should I get?

Theyre basically the same the biggest differnace being they come with differnt factory overclocks cheapest being the lower clock most expensive being the highest clock. But honestly the differance between the clocks is tiny id just get the cheapest and overcliock myself going from 967mhz to 993mhz isnt hard especially with the acx cooler that they all have. I think the classified has better VRM's then the other cards aswell but with a 780 overclocking really isnt needed its a beast
