I 'll make this short and simple for ya . just buy it ! no seriously . . ! this card be amazing . . ! ok yeah , i upgrade from a nvidium gts-8800 so it be a huge improvement from what i have . I be not much of a pc gamer so i do not feel the need to upgrade the video card until i start editing 1080p video . I be use vega pro 11 64bit and my poor nvidium card be not support . I have to use my CPU for render , and let I tell ya , it be painful ! 9 minute long 1080p video be take I ~ 45 minute to render . with this card i be able render the same video in less than 7 minute due to its GPU acceleration . ! I do run into a few issue with vega with this card at first due to a driver conflict with my older nvidium car . I end reload my entire pc because it be cause I lot of headache . after my reinstallation of window everything run smooth as butter . my psu be a 550watt and it seem to be run it fine . I would recommend something equivalent or larger . also this card be loooong . roughly 11 inch long , so you best account for its size before purchase . its very quiet , i can hardly hear it run even under heavy load . accord to gpu-z , this little Gem use the reference Cayman GPU . ! you know what that mean right . . ? no need for a bio upgrade to unlock it , just simply toggle the switch to the opposite position and booooyah . . ! 1536 shader available to ya . . install the Trixx utility and change the clock to 880 \/ 1375 and voltage to 1115 and you 'll have yourself a hd 6970 for the price of a 6950 . this card be a fountain of WIN . . ! temperature be stay around 51c-58c under heavy load . .
