I buy this video card base on amazon review . let I just start by say I build my own computer for many year , I know how to install new hardware . the first card install fine and work for about a day before I start get artifact -lrb- green box -rrb- on the screen . after 2 day the video driver would crash randomly . I exchange this card with amazon . the second card would not even boot ! I try everything and I could not even get a image to display . so I return that as well and go back to my 6870 , which work perfectly . from my experience , I would not recommend this card , it be noisy and defective .
