The MSI lightning has triple voltage tweaking which just means sharper voltages on the core & memory. Also every nvidia card is limited to 1.175V on the voltage but the Lightning has an LN2 bios which was allowing to go higher than 1.175V but MSI had to modify that bios because nVidia forced them to do that.
If you want to unlock the ln2 bios you have to mod your card by flashing the bios with an unlocked bios.
EVGA's cooling is nothing compared to Asus/MSI.
If you don't want to do modding & all that stuff and want a pre-high overclocked card get this one.

Been telling it earlier that this card boosts to 1254MHz default. This is really the most quitest card of all gtx 680's. Buying an evga over this one is stupid and evga just sucks.
You can't overvolt or anything like that with the Asus but it's not needed. Overclocking them are easy.
Core clock: just increase it step by step with 10MHz and play your game - until your game crashes just step 5-10MHz lower
Memory clock: just bump it to 6800MHz and run the evga oc scanner x program to check if there are artifacts - If not just increase the memory freq, If it's artifacting go lower.
The evga signature gtx 680 sc2 or whatever is just a very hot card. It's running 14° higher and 20dba more noisy.

I don't really know how you even could succeed to advise people buying a very noisy & hot card which doesn't have room for OC'ing anyway.
