replace vapor-x 5770 in MCP . . want a 6xxx card for the 3d and 240hz \/ \/ 120hz . thanks to AMD 's series ' screwy name system this seem to be better than a 5770 but not as good as a 5870 . why this card would not be a upgrade version of the 5870 I will never fully understand ... Card be large and I have to reroute my radiator line to get it to fit -lrb- compare to non-reference 5770 . not that big compare to 59xx but smaller tower will not work with this card . it come with the power adapter if you need they but I think all PSU 's come with they nowadays . should have come with the display cable and xfire cable . this mean that you 'll need to purchase the extra cable if use two hdmus out . I have a lot of problem set up and get the 5770 to ever work properly . this card be easy to install on the driver end . with every edition of catalyst it seem that it get more complex and add new bug while the old bug get fix . I be still have issue figure out how to get the display the way I want they while Windows fight to take control over they as well . that be not the card 's fault though , that be AMD 's poor software . the fan be loud when max out but that be to be expect . very quiet -lrb- I be compare it to a powercolor for reference -rrb- for gaming and usual use -lrb- assume you be not overclock it -rrb- .
