What's a GPU that can SLI with a GTX 680 MSI Lighting?

So, I'd like to SLI a 2GB GTX 680 MSI Lightning, but the thing is that THEY'RE ALL FRICKIN' GONE! Well, except for refurbished ones but I don't really trust those. So this has me wondering what other GPUs can SLI with it. I'm looking for something with similar performance and still affordable. Welp, thanks in advance!

You can SLI with any other GTX 680 2GB models.
Also look at ebay and see if theres any second hand ones with minimal use?
Other 680's that would be similar would be the MSI Twin Frozr or even the Gigabyte Windforce
In my opinion it would be best to get another lightning, the refurb ones do come with a warranty , so have a look what the conditions are on the warranty and if they replace them then go for it.

As long as it is a GTX 680 you should be fine.
