This is a fantastic card. Good quality. It runs extremely quiet and cool. Max O/C is 2100Mhz @ max temp of 72* under full load @ 450 watts of power. This nearly 10* cooler than the non-hybrid but w/o all of the fan noise. My non-hybrid overclocks better 2150Mhz but at 83* max load of 450 watts and quite a bit of fan noise about 70db compared to 40db on the hybrid. It's well worth the small loss of Mhz just for it's quietness/cooler temps and less that 3fps loss in gaming apps.
