I recommended a friend to buy one of these for his build, but it turns out that it doesn't come with an onboard fan controller, and the fan was running at 100% all the time (No amount of driver hacks, rivatuner, BIOS mods would do anything to change that). He had to fight to get a refund (as it wasn't faulty per-say, apparently it's default behaviour from gigabyte), but fortunately they took it back in the end.
Although the zalman cooler used on this is quieter than the stock cooler would have been (which is what drew me to this card in the first place), it's still to noisy to run at 100% all the time.
So if noise bothers you, avoid this card!
