AMD radeon crossfire
radeon r7 260x
radeon r9 290x
can it be done?
r7 is gigabyte and the r9 is MSI if that matters?
 
Solution
RAM is not additive in CFX/SLI as it is mirrored and will use the lowest spec'd card. Example: 2GB+2GB=2GB. 2GB +1GB = 1GB.

These two cards cannot CFX anyway.

oh right ok, thank you.
i'll be instaling the 290x then!
but if i were to geet another 290x sometime in the future would it matter if i use the MSI one i have now with, say a sapphire 290x?
 


Brand won't matter but be sure they have same amount of RAM so it's not wasted.
