Doubt Asus has fixed this as they made the heatsink bigger with the 1080Ti. I've got a Aorus 1080Ti Xtreme being delivered tomorrow will be interesting to see how it sags because its a big 3 fan card as well. Regardless I'm pretty excited to get it installed. I've always gone with EVGA in the past and I had a EVGA ftw3 preordered but couldn't wait the extra month.. felt like EVGA dropped the ball with this release.My MSI Gaming X arrives tomorrow. I've had the MSI Twin Frozr coolers in every iteration of my upgrades since the 680 (970, 980, 980ti) and they are just so solidly built. I've had sagging issues in the past with Asus Strix cards (Had a 970 for a few days) so I stay far away from those even though they look cool. They've probably since corrected the sagging issues but MSI has never let me down so I stick with them.
The MSI 1080Ti card looks like a great option though I would of grabbed it if they had it in stock.
