I have a CrossFire question regarding MSI' Mid-Range gaming Motherboards and more specifically the B85-G43 Gaming MOBO.
My RIG CPU: Intel Core i5 4670k Motherboard: B85-G43 Gaming MOBO Current GPU: MSI Radeon r7 250 OC Future GPU's: MSI Radeon r9 270x Gaming (x2 in CrossFire)
Okay so the MSI Gaming motherboards are heavily advertised as CrossFire Ready.
The B85-G43 Gaming MOBO has the following for multiple GPU CrossFire setup PCI-E 3.0 x16 PCI-E 2.0 x4
So I am guessing from these specifications and being advertised as CrossFire ready, the PCI-E transfer rate for Dual CrossFire setup will be x8 x8?
Can anyone please confirm before I waste my money on 2 GPU's

No. That motherboard technically supports Crossfire, but the second card will only run at PCIe2.0x4. Generally you want one that's advertised as being SLI-ready, because the conditions are more stringent.
I'd suggest getting a Z87 or Z97 board - you'd also be able to OC the CPU, which you can't on B85 really.
Basically long answer short. My only real feasible and recommended option would be to buy a more powerful single GPU.
I hate you MSI!
Anyone had any success running CrossFire with x16 and x4
