Stay away from all sapphires but the toxic editon (maybe), as I too have the bios throttling issue with my vaporx.
I think with the better cooling (heatsinks on the vrm vs just pads with the vapor) of the toxic edition and maybe a different bios it doesn't have the same problem of the vaporx.
is more of the vapor-x issue.. it's bios holding back, trying to keep temp at 70c..
sapphire 280x dual x is the bomb... 740-750kh/s easy..
