HD6690 & HD5970 CF?

[clazz]

Hello,

Sorry for such a silly question, but I'm curious,
can a HD5970 & a HD6990 be CF'd together?

if so what are the complications involved and would performance be better running both on a crossfire setup or just having the single PCI-e 6990?

Thanks for your time in advance

Ok, so only those in the same model rang. 5000, 6000 etc. Thank you
