The Gigabyte Windforce cooler is probably the best (or second best) GPU air cooler, then there's the top-end EVGA one which is basically as good, then you have a variety of dual-fan coolers from a variety of manufacturers such as the MSI TwinFrozr, and the XFX DD. You probably won't need to care too much about coolers as long as you're not manually overclocking, as all decent manufacturers include a cooler which should be safe for the card at the clocks they sell it at.
Don't be afraid of the DD, as it's not a bad cooler, it was just paired with a really hot chip and had it's thermostat set higher than ideal. It would have been absolutely fine and able to hold impressively low temperatures all things considered had I manually forced the fans to go faster, and hadn't kept it melting in an awful case for 9 months.
By the way, my brother currently has my old DD cooled card in his computer, and that's in a pretty similar Thermaltake case, and it runs at perfectly fine temperatures, at least according to its definition of fine.
