Personally, I would keep the 1080ti's for now and keep them until some kind of refresh version in the future, 2 1080ti's is still a dang beast, is it worth 800 bucks for my aio, Absolutely yes, every single penny, Looking into evga's shopping area, the hybrid version of the 2080ti cost to much, 1399??? can kiss it, 2 1080ti with xoc bios would eat it for lunch, so therefore I am holding back on this, until some kind of refresh version comes out in the future, I am holding off of the 2080ti this time around, looking for something different in the future, not worth upgrading, that's just me though, would love to test the 2080ti though but thinking about passing on this time around. Not only that, My runs Extremely cool, Sometimes underneath 40c under full load, since its going to get warmer here, higher temps will be very apparent, and thats with the XOC bios, so that is extremely impressive from an aio setup and also running a push and pull configuration with 2 scythe fans rated at around 110CFM and yes they are always running 100% at all times. Think about it: 2 2080ti hybrids for a Whopping over priced 2,800,00 usd, OR 3 1080ti Hybrid's With XOC bios(Through Bios Flashing) for Only 2,400,00?? that's 400 usd difference, The difference is clear as day, if you want price to performance ratio, the 1080ti equipped with XOC bios or Shunt Mod is KING!
