I have the sapphire toxic 4850 512,b, want to crossfire it up. Do i need an indentical card? I know you do for sli, but was told that for xfire you can use different ones as long as the are the same series.
I want to get the powercolour with the custom cooler as its cheaper and i know i could OC the GPU to the same speed as the toxic.

Thanks.
 
so long as the card you get is another 48*0 it will work. you can get a 4870 1024mb if you wanted - xfire will reduce that card to match the 4850512mb tho, eg downclock and disable 1/2 the memory. also note that by default xfire will downlock the toxic to match the powercolour cards stock speeds. this can be overridden in ccc now to run both cards at whatever freq you want (so long as both cards running the same)

eg, im using a saphire ultimate 3870 (built by saphire) and a his 3870 from launch (built by ati) xfire, works fine.
