It'll work as long as it's two 660s and they're SLI compatible. You might need a bridge, though.

Other questions you need to answer are do you have a good enough PSU to power two GPU's and does your motherboard support Sli

Right, I forgot about that. You might want to upgrade your PSU first.

You'll see SLI compatibility listed on left and no, they don't have to be the same brand. If they have different memory amounts, only the lower number will be used.

Here is Guru3Ds power supply recommendation:

GeForce GTX 660 - On your average system the card requires you to have a 450~500 Watt power supply unit.
GeForce GTX 660 SLI - On your average system the cards require you to have a 700 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina.
