MSI HD7970 Lightning Boosted Edition 3GB or MSI GTX 680 Twin Frozr 2GB

[PenguinzHD]

Struggling to pick between these two cards, I intend to attempt to overclock (I'm a beginner). Being a beginner also means I don't really know what I'm looking at, I have an idea, but not much. Any help with which ones better? Here's links to them on Overclockers if it helps.
