SLI or Singular Card

I currently have one MSI 660 ti and I was wondering if it would be worth grabbing a second for around $200, or just purchasing a different card for around the same price range. I'm also wondering how much of a performance increase I would receive with SLI, or with a different card.

a single 660ti is only a tad behind a 760. A 660ti sli setup will be more powerfull than both a 760 and 770. The only caveat is that your limited by the vram in sli, so if the 660ti's are 1gb variants you may struggle at high res, with high ingame settings. Most 660ti's are 2gb though, so 2gb is enough for 1080p and all the bells an whistles, and with an sli setup with 2 660ti's it will be on ultra settings, and play smooth as butter.

Someone else who has used higher res monitors than I can probably answer that part very well, as I am running 1920x1080.

But keep in mind, from what I understand, the ram does not get doubled when you SLI or Xfire. So 2 2gb cards is not 4 gb, but 2 gb.

Well the RAM isn't doubled in the sense that one card can't use all of it, but both cards will still use the RAM.
 
Two cards in SLI will generally perform better then higher end cards in single set and ASUS just proved that with their Mars card which is based on the 760 GPU. Asus put two 760 GPUs on a single PCB and this card is the equivalent of two 760's in SLI and it for the most part out performs the GTX Titan.
So yes two 660Ti's will give you the performance boost to play any game maxed out on very high if not ultra settings. since you have one 660Ti then you least expensive way to increase your game performance would be to add another.

I had previously read that the RAM isn't doubled, that's why I was wondering about how it would contend. Thank you all for your help and I'd like to let you know that all of your answers helped me reach my decision. Thanks a lot!
 
If you went to a 2560x1440 monitor the 2gb cards will do ok but a 3gb card would do better. To go 2560x1600 you want a 3gb or 4gb card.
A monitor can only use the vram of the card that is connected to. There is work being done on the vram of the second card being used but that hasn't come out yet.
