Will a GTX 670 go in SLI with a different GPU?

[dlp12]

Hi. I just bought a GTX 670.
This one, specifically: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127685
Let's say I wanted a 10 or more FPS boost by adding another card for SLI.
If I purchased a different GPU, like a 500 series card; would it benefit me in FPS, or even work?
Would I have to have the same clocks, voltage, etc.?
I was thinking this card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130652

A 670 can only SLI with a 670. It can be a different manufacturer's 670, but it must be a 670. You can however have a 500 series card run Physix, but you will not need to connect the cards together with a bridge. Hope this helps! God Bless and happy gaming!

By the way, would buying that 550ti for PhysX help me gain FPS any?

No way Jose no way, sorry just kidding. Yeah like monoproelio just said you can only sli two cards than share the same gpu, even if one has higher or lower clocks, but it has to tbe the same. Otherwise the 2nd card will be used only for physics. Regards

Only in games that use PhysX, like these - http://www.geforce.com/hardware/technology/physx/pc-games When choosing a PhysX card make sure to go for more CUDA cores over raw gpu horsepower!
