the title says most of it all. I have a HD 6850 and an AMD 2x4 640 CPU. I know neither are particularly powerful, but with the recent value hike of BTC i tink they can turn a profit, or at least be an efficient way of buying BTC with my electrical bill.

from my research, the HD 6850 should attain about 170-250MH/s for bitcoin at around 130w. with litecoin it would likely see around 250 kH/s. I would try to underclock the memory and OC the GPU to make the best H/w ratio here.
I cant find much info about the CPU for litecoin mining, but would assume it can operate in the 20-50 khash/s range.
any suggestions or scripting i should use?
