this be a power-hungry , video-processing beast ! I can stream -lrb- and decode -rrb- H. 264 video at 1080p on one monitor while play StarCraft 2 at max setting -lrb- 1920x1200 -rrb- on another . I honestly do not know why they sell graphic card with more power than this . oh , and the bad part ... it blow up my 600w Thermaltake Purepower PSU after two day . recommend a BIG power supply for this bad boy . use a Corsair GS700 now and everything be great !
