Sorry, you guys had your day with scrypt. These days you gotta go green (nvidia) to earn the green (money) :p

That being said, the high end maxwells are delayed till early 2015 at best it seems. 750ti's will be relevant for quite a while.

If you don't want new hardware, try checking new algorithms. AMD had x13 for weeks before nvidia, and you guys could have made a killing renting hash on nicehash, or going for an instamine on x13 coins.
