Ya i hadnt thought of the electricity costs.. perhaps this isnt for me

I guess in general i was just looking to mine.  I figured the monetary side of things wasnt going to pay out that much but just wanted to know if there was any mining software that would utilize my CPU instead of GPU.  I had seen a few adds and most were saying GPU so i wasnt sure if i could use my computers at all since my graphic cards werent up to par.

So I've got 2 systems.  Both have an 8 core cpu but the gpu isnt that great in either.  Will the mining software be able to make use of the CPU cores and will they calculate a comparable number of blocks in relation to a GPU?  I believe one system has a 750 Ti and the other a 1050 Ti?
