be look forward to upgrade dual ATI 4650 card to a superior single card . I run triple monitor and want better single card performance with triple monitor support since the motherboard do not support crossfire . after research higher level card and conclude many require a higher power supply than my 460w I decide the 6770 be the GPU I need . I choose this card base on the XFX name , a good after rebate price of $ 88 and mostly positive review . after install and find triple monitor could not be support by a Displayport to HDMI cable that I also purchase -lrb- the Displayport to HDMI cable must be a active or power cable that cost 30-50 dollar -rrb- I decide to install the card in a identical second pc in the house . both pc 's have core i-7 and could benefit from better graphic card . unfortunately the fan noise in both installation be unbearable as a few have also write about so I be return it . for I I find this to be a major flaw in the design of the card as the noise negate any positive of the upgrade in performance that I might have gain . I hope I be able to find a better build -lrb- quieter -rrb- 6770 card as the spec for the 6770 be optimum for my pc 's .
