The above is planned for another big cup in the summer... Challengers will remain similar format... as Michael said the current format is not that bad when you start benching...
How many divisions do you require to achieve that goal? Divs are are nearly identical from Round1 and indeed the FX octacore was a fuckup first class by AMD in efficiency...
However you should be able to compete easily in 3D11 (physx) and GPUPI right? Only 2 stages are per core to balance things a bit more... no idea how to make it more fair for everybody
