I've been using AB for about 3 months now with 4 cards and I like it. It allows me to overclock, monitor temps, and set a fixed fan speed.
AB
PROS-
nice GUI
can save profiles
monitor temps in system tray or task bar (whatever thats called)
make custom fan speeds
CONS-
can't OC more than Trixx
takes longer to switch between cards
I've used Trixx for about 2 days and it seems to do everything AB does with a little extra.
PROS-
same as AB (except monitor temps outside or program)
can over clock some cards MORE than in AB, for example.
(5850 in AB can only OC to Core:749MHz or so in TriXX: Core:1000MHz) what's up with that?
allows me to change VDDC? whatever that is. (haven't used it)
Allow more custom fan options.
cleaner and easier interface
drop down in main window to switch between cards!!
CONS-
doesn't have option to monitor temps in the task bar only in the program interface (that I know of)
that's about it.
What do YOU miners prefer AB or Trixx???
