From what I've read, the main benefits of the 1080 can only be seen with 1440p/4K gaming, so if you're already getting great performance with your SLI setup then you may be okay for a while. I mean are you going to see a world of difference with 140fps versus 120 (asks the guy who has no experience with either)? I mean yes at the end of the day the 10x0 cards are very powerful and great bang for the buck but you're pretty set for a while. A single 970 is pretty damn powerful and SLI support is common on most major releases. I just think given the hassle of getting rid of the 2 cards then trying to sell them (Which are going to have lower return rates once the 10x0 cards are actually released) and then having to probably spend more money on the card isn't worth it at the end of the day. But again, it's your money, at least it is until I get that algorithm working that can tap into bank account numbers via Xbox Live Gamertags...
