I'm excited to see how the 290x will fair with water cooling as well.
Has anyone else had problems with certain games where you get fine fps and then the second you wiggle your mouse the fps drops to 7-15 fps depending on how fast you move your mouse? I've had this problem with audiosurf (not a big deal because I usually just use the S and D keys) and Dead Space 3 (made the game unplayable) I just discovered that turning off "enhance pointer precision" in windows fixes the problem entirely... FrankieOnPC also says it improves your accuracy in game....
EDIT: I agree you'd be crazy to try and OC the 290x with the stock cooler. I wonder how different the temps would be if you replaced the fan/wired it to the mobo instead so it's not stuck at AMDs preset 55% max speed?
With they stock cooler they were trying to push that cooler to the max when on the Uber BIOS. Something about saving costs. Still, ridiculous card. Matches or passes Titan in most cases for much, much less. AMD has a winner.
