I already have 2 660 ti's and was thinking down the road when I want to get a little more graphics power, should I just upgrade to a nice gtx 700 series or would adding an additional 660 ti be just as good? Primary use is gaming

Since you already have two 660s, I'd go for the third and save your money for an 800 or 900 series GPU when they arrive. Just make sure your motherboard and PSU support a third card.

3 way SLI gets really poor scaling (meaning in third card will not help much performance wise). I would recommend selling the cards and going for 770 4 gb sli or better. Also, I wouldn't do this setup unless you have QHD screen (1440p) or 144hz TN panel.

I'd stay with what you have till the 800's come out and then sell your 660 ti's and buy either the 870 or 880... Adding a 3rd card will add very little if any performance to almost all games... Very few games support 3 way sli.

Good to know, I'll prb just wait for the 800s then, just got a Asus z97-ws and the i7 4790k so I'm set processing speed for a while

Though dated, in this review it shows the scaling of three-way SLI with 660 tis (I know you're using 660s, but this demonstrates where the good scaling comes into play) as increasing as details are increased:

If you crank everything to Ultra, this is where you see the performance gains with the third card.

The more you make the cards work, the better the 3-way SLI performs.

Well that's what I really want to be able to do is run everything on ultra
