They look very very similar spec wise, but the second one seems to have different heatsink/fan/case. Could anyone take the time to tell me the pros/cons of them compaired to each other?

the first one is a non referece superclock edition. the second is a reference cooling super clock edition both are factory overclocked. the last one is a non factory overclocked stock standard edition. it really depends on the cooling you want the first one would offer better cooling how ever it might blow heat into your case the second one will force it out of the back and the third is the same as the second. blower style coolers.

So, if i understand correctly, since the last one has better Base clock (980) of the 3 and isnt overclocked by the factory it has even more room to outpreform the first two?

I prefer factory OC compared to the one with the better base clock but the one with the best bass clock would have more room to outperform the others.
