First. I have owned many cards that someone could call "BIG" size wise. 8800GTS, 8800GTX, 8800Ultra, 7950GX2, even a monster 295X2.
Nothing, absolutely nothing prepares you for the size and weight of the Aorus 1080Ti Xtreme. The cooler alone is bigger and havier than a FuryX (with the AIO) or the MSI GTX1080 Armor (had one last year).
It even dwarfs and outweights my old 295X2. So make sure you have good motherboard with metal reinforced PCI-e.
Second. Is 2.5x height tall. Which means I cannot use my PCI-e for the wifi adapter, which is very old one and cannot work off a PCI-e x8. So Is now sharing the same PCI-e slot with the M2, and is working at x8.
Unfortunately the Gigabyte X99 Ultra gaming second M2 is short one and cannot fit the M2. Ordered and waiting a USB wifi tomorrow.
Third. Beautiful card. Especially when someone sets the lights on. That glowing eagle on the back and side plates are amazing.
Fourth. Fan's aren't working on desktop mode
Fifth. The Aorus utility seems pretty descent. The card is set by default to gaming for 1763 clock. But when you click the OC mode, it sets the card 1962mhz (haven't explored further with MSI AB etc).
We soon find out.
