Should I SLI?

    But the law of diminishing returns certainly applies, so I would not get double the performance, although it would be a significant boost I suppose. Also all that is just silly. Why would you need anything beyond 4k?

    So basically, if I were to SLI my 970's I would see a very minor increase in performance, but I would not truly be utilizing the second gpu unless I was pushing a much higher resolution, therefore making it pointless?

    Yeah but you can round it off and say double :stuck_out_tongue_winking_eye:
    Exactly. Only very few games which are extremely GPU intensive will see slight performance gains but not worth the cost. If you upgrade your display or add more displays then you will benefit a lot from SLIing your GTX970.
    If you have two r more 4K displays connected to the same system(I don't know, may be for some hardcore gaming/designing) you are in fact multiplying the number of pixels by the number of displays. More pixels demand more processing power.

    I was going to reply to @NazgulStig with regards to the double performance thing saying it wasnt that much, but some of the links I found contradict it, so I will simply post those links and leave it up to you to decide. Personally I still say that SLI for 1080p resolution is really not needed and more of a gimmick unless you want to crank up the AA and/or future proof your machine or go for a higher resolution monitor later.

    As was said before, you'd almost be better off waiting a year or so and use the card you have for now. Then once the price drops after they've released new cards, pick up a 2nd one at a lower cost and SLI that baby for another few years. Going that route should easily get you to 4 years like you want.

    "Double performance" as I clarified later on is just an approximation to make the conversation simpler. It doesn't mean you will get double fps all the time, there are other limiting factors and things become close to that double performance only when you break the limit of what your single GPU is capable of doing. One good example from the techpowerup link you posted: Link
    As you can see the performance become close to double in 3840x2160 whereas it is similar in 1600x900

    My point exactly.

    I will say that on my system with my 3930k and single GTX780, I was running dual 1080p 60hz monitors. when I got my dual 144hz setup my FPS really struggled on ultra settings. I had to drop down to high on several of my games. after getting my SLI GTX780 I was able to gain back every bit that I had lost in FPS and gained a bit in some areas. but I still don't think that SLI is worth it with 2 brand new model cards. I waited until after the GTX9xx cards came out and I was able to find a matching GTX780 for 225 bucks less than the first one I bought.
