Been trying to find out more about this scrypt-jane news... Anyone got a link, info? Or, willing to write an overview of what it is?

scrypt-jane is a feature under development and some fearless people are trying it out. It is used in Yacoin and other Alt-coins and currently nVidia cards have an edge (around factor 2) over ATI cards. Hence the mining returns (payouts) are higher - and power costs are reduced also.

scrypt-jane currently does 32768 iterations and requires 4 MB of memory per hash. scrypt does 1024 iterations and requires 128kb per hash. This causes scrypt-jane to work most efficiently on mid range GPUs with 2-4 GB of RAM. High end nVidia GPUs are a bit faster, but only slightly.

Thanks for that! I might try this out.

my 2x Titans [are] getting 700.XX khash/s per GPU (1400-1430 khash/s for both cards).

Very good numbers! My GTX 780Ti only yield 540 kHash/s each (on Linux, with a mild BIOS based overclock).

We've got a 780 Ti reference getting 750 khash/s, and a 780 Ti Classified getting 720-ish khash/s (Classified doesn't like undervolting). I can get about 660 khash/s from my 780 Classy. Anything higher (I can get up to 730 khash/s @ 1380 Mhz) uses an ungodly amount of wattage. Custom BIOS really lets the Classy loose with mining.

I believe they posted in my Titans @ 1350 khash/s thread I linked to above. They are on stock BIOS as well.

We're using the "Temp Target" trick I figured out to undervolt the cards even further than MSI Afterburner/PrecisionX will allow u.
