Im kinda confused i have a 3870x2 if i wanted to go tri-fire and add a standard 3870 how would it work? if you crossfire normally the fastest card will run at the slowest cards settings but how can this work in tri-fire? 3870 X2 825mhz / 1800mhz ddr3 3870 725mhz / 2250mhz ddr4 What card will default at what clock speeds / memory speeds? cos either way one either has to go up or down lol? like i said CONFUSED would it just end up like 725mhz/1800mhz ?
