Hmmm it just looks like crossfiring GPUs comes with more cons than pros.... 

 

it more of the mobo support for SLi or not

 

since 290/X removed the CF fingers

 

the PCI-E lanes is def more important

 

 

the old tale of running fine with PCI-E 2.0 X4 is now false

the R9 295x2 is internal lanes for sharing data between the 2 GPUs but the link to the RAM and CPU will be using the PCI-E x16 lanes

 

the only concern for using the 295x2 will only be low end CPU like the Pentium and i3

 

i5 4670/4690K is the minimum you can use with the 295x2

i found proof from Cheddle that dual 290/s on a non-SLi board will clip the performance of the 2nd 290

Hmmm it just looks like crossfiring GPUs comes with more cons than pros....

Budget? Uses? Currency? Location? Operating System? Peripherals? Monitor? Use PCPartPicker wherever possible.
