EVGA has already Tweeted they are working towards custom cards available at launch. Supposedly partners already have these in hand.
I want to see which card you are reviewing and will publish on 27th. The founders edition sampled by Nvidia or the custom version from partner like EVGA. The pricing difference of USD 100 is significant. I don't like this trend of mid-range dies creeping up from the days of GTX 460/GTX 560 Ti at USD 200/USD 250 to GTX 680 at USD 500 to GTX 980 at USD 550 and now this so called Founders edition at USD 700. AMD has also been guilty of increasing prices from HD 6970 at USD 369 to HD 7970 at USD 550. I hope Polaris is competitive enough in perf and price to bring some price reductions in Nvidia's cards.
If the 1080 can overclock past 2Ghz easily on water I will be grabbing one just to play with
