Dont need a crossfire card to run crossfire?

post #1 of 6
Thread Starter 
ok, ive read around and ive seen a couple things saying that for the xpress3200 chipset you dont need a crossfire card to run crossfire, becuase the 3200 chipset can do all that internally? does any1 have concrete evidence.. cause my x1900xtcrossfire is ordered but i can get the x1900xtx which is faster and actually cheaper.. and in that case i will eventually run 2 xtx?

As far as I am aware mate you need at least 1 master card but the second can be what ever you want it doesn't even have to be the same model card

Supposedly this is true but is still waiting on a catalyst driver release to suppoert it and may be limited to the X1800 and X1900 series only.....would like to see official word on this.

Actualy I believe its limited to the x1300 and x1600 series.

Shame the x1600xt has a 128bit mem interface, would of been great crossfire cards, cheap as dirt too, a x1600xt can easily be aquired for 120-140 dollars, so 280 bucks for a decent crossfire set up is not bad, I wonder how two x1600xts stand up to one x1800, that would be an intresting benchie comparison.

You Will need a Master Card to Run that x1900 in crossfire. The X1300 and X1600 series dont need a master card as Crossfire is dealt entirley through the Catalyst Drivers.
