I really like this card for bitcoin mining, I can run my phoenix mining script and it doesn’t affect my processor speed allowing me to use my computer AND bitcoin. I big plus of the 5770 is the low power compsumption, I didn’t have to upgrade my power supply. I kept 430 W power supply which I was using before with my Nvidia 9500 GT with my Dell 518.
ATI HD 5770
I got it from Amazon.com a great deal.
Here is my bat file.
phoenix -k phatk DEVICE=0 AGGRESSION=6 VECTORS BFI_INT FASTLOOP=false WORKSIZE=256
I am getting over 175 mHash/s without overclocking.
This is the power supply I am using, its only a 430W power supply which is nice. I wanted to use the lowest power supply possible.
