not even close!
that will cost you... what? 30.000-$40.000???
it will make like 45Mh and with that you can mine 400LTC/month, well not even that since difficulty is rising every 3 days for LTC... even if you don't pay electricity you will still need like 7-8 months to ROI.
so you wan't even return half of what you invest you will be run over by scrypt asic and they are around corner.
stay away from gpu-s IMHO.
pay attention on this:
Scrypt asic

https://www.kncminer.com/Well i said "millionare" saying "get a lot of money" no of making "10+ million $" anyways, LTC was not protected to ASICs or something like that? (sorry if my english is bad)... how much time for that ASICs to appears? they will make grow up a lot the difficulty? they will be avalaible for purchase and ship fast, because in bitcoin ASICs you maybe have to wait like 1 years to get your ASIC and now they aren't good because with a big one you make like 800 usd per month?.
Think about this.
400 per month.
Let put 8 month to december.
Suppose because of the difficulty you will make the haft of the coins in 8 months.
Suppose LTC grow up to 300 usd.
400 * 8 / 2 = 1600 * 300$ = 480.000$
It's a very high production, and i think it can be more.
Thanks for your opinion, i want to hear a bit more it's intresting talking about this and say to mee if i'm right or not. Good luck, blessings!
