Mining with multipool and nvidia titan GPU

[erotavlas]

Hi,

I'm new of mining and bitcoin. I would like to know if mining is still profitable in term earning/cost (hardware and electricity). I have three video cards and solar panels, but I don't want to waste energy. The video cards are: nvidia geforce gtx Titan GK110, geforce gtx 670 GK104 and geforce 8400 gt . I would like to use the mining multipool https://www.multipool.us/index.php. What is the best software for mining on linux? Cudaminer or other?

On the web I found a lot of configurations for various GPU. Are these parameters good for Titan? cudaminer -r 10 -R 30 -T 30 -H 1 -i 0 -m 1 -d 0 -l K14x32  --no-autotune -o stratum+tcp://eu.multipool.us:12222 -u Username.Worker -p Password or these are better cudaminer -d 0 -i 0 -C 2 -l K14x32 -o stratum+tcp://eu.multipool.us:12222 -u Username.Worker -p Password?

What is the best scrypt or Scrypt-Adaptive-N?

I'm sorry for my trivial questions.

Thank you

scrypt and scrypt-n are and will be asic raped soon. X11 is full of FPGA devices. try out X13-x14-x15 or cryptonite. to my knowlage all are nvidia mineable. i know cryptonite is but cant say for sure about the others.
