EVGA GTX 660 SC SLI Compatibility

[DeviousBanana]

Hey all,
I've never had to deal with none identical sli cards but I recently bought a second EVGA GTX 660 off of a friend who upgraded and the part numbers don't match but I can't find a difference or very much about the second card for that matter.
First Card: EVGA GeForce GTX 660 SUPERCLOCKED 2048MB GDDR5 DVI HDMI DP Graphics Card
First Part Number: 02G-P4-2662-KR
Second Card: EVGA GeForce GTX 660 SC
Second Part Number: 02G-P4-3069-KB

They're both 2 GB superclocked EVGA 660 but I can't find the clock speed on the second card.

Will these two cards be SLI compatible? And if yes will there be a performance loss?

Thanks.

Check this out, seems like the second card with the part number 02G-P4-3069-KB is a Best Buy special or something.

exclusive superclocked (EVGA has so many different versions sometimes you wonder which one to get lol)

It has an extra 13MHz higher base clock than standard superclocked version 02G-P4-2662-KR which has a base clock of 1046MHz vs 1059MHz. Both are 2GB cards, they will work fine in SLI.
