Example of high N-factor scrypt coins? And what hashrate are we talking about (with 660 Ti?) for these coins.
Yacoin is the original (oldest) scrypt-jane coin and currently has N=32768 (Nfactor 14 I believe), switches to 65536 in May. An overclocked 660Ti can deliver 3.7-3.8 kHash/s. An OC GTX 780 might do up to 5 kHash/s, but the additional gain is not worth the additional price.
