Im not sure it will change much. With the last N change my 7790 lost 80% hashrate and my 7950 lost 40% hashrate, the funny thing is Im getting more coins than before. The CPU miners where also affected by the change (I guess 50% drop). IMHO the GPUs with lots of memory like the 7950 (3GB) are the winners, while normal GPU cards with 1GB RAM like the 7790 and CPUs are the losers. I guess it ill take another 1 or two N changes to hit those High End cards harder as well, but the small GPUs and CPUs are hit even worse with every N change. So I will probably get an AMD Hawaii (4 GB RAM, 512 bit memory Interface) for YACoin mining
