Crossfire question

[l8oss]

so i have xfire hd 5770's my buddy has a 5870 he will give me

my mobo can do 3 way sli/xfire

so my question is can i 3 way xfire 2 5770s and a 5870

I think it's not possible. The first 2 numbers need to be the same in order to crossfire. If your buddy had lets say a 5750 it would be possible to crossfire.
An exception to this is the 5750/5770 can be crossfired with 6750/6770 because they are the same cards just under another name.
Also check this for future reference http://cdn.overclock.net/0/06/068d19bb_AMD_CrossfireX_Chart_1618W.jpeg

yes I believe this is possible bc 5770's can be tri crossfired and seem to work pretty well doing so....according to AMD website you would not need an external bridge to crossfire a 5870 with a 5770

external bridge?

 

[drums101]

the external crossfire bridge between the two cards...they should come with the card but you do not need them...here is the chart I was looking at
