I've been looking around and according to wikipedia (http://en.wikipedia.org/wiki/Mobile_PCI_Express_Module) which I hope is wrong it says that MXM 3.0b only supports memory bus up to 256bit. With HBM just around the corner could mean that mxm 3 is finished as HBM1 has a 1024 bit bus and HMB2 will be similar. With HBM1 being in AMD's next flagship desktop and most likely mobile gpu cards it means that there will be no more gpu upgrades and the limit will be the 980m. Don't get me...
End of mxm 3.0b imminent?
