So, right now it seems a 7970 can get 240 khash/s and a 2600K can get 40 khash/s right now at N factor being 9. This will change to HALF on 25 June so not excellent news there.

So the same card mining LTC would be 77.25 USD / month.

Mining YAC with CPU will bring about 19 USD / month. Mining LTC with same CPU will bring like 7 USD / month so not worth it.

YAC mining is worth it for CPUs ? Worth paying for a 4770K right now ?
