GTX 670 sli question

[pacobart]

I currently have an EVGA GTX 670 Superclocked + graphics card. I want to buy another to sli. This card is out of stock everywhere, I'm assuming they stopped making it. Can i buy a reference GTX 670 and put these 2 in sli or do I have to have another superclocked + card?

You'd be able to grab another 670, but they'd have to both run at the same clock speeds, so unless you overclock the 2nd card, or get a different OCed card you'll have to downclock the card you have now. But it will work just fine with a different card.

You don't have to get the same clock speed, or down/over clock, but it would be advisable.
