R9 390x, msi vs sapphire vs asus vs xfx

[MilesOrton]

As the title says, which one would you go with is there an actually difference besides msi being 256 bit (whatever that means)

The graphics cards

All R9 390X have the memory interface at 512bit.
Amazon just have the specs wrong for that MSI R9 390X card.
Main difference between the R9 390X is the cooler used and the PCB.
The sapphire R9 390X or the Powercolour PCS+ R9 390X would be the best for cooling overall.
