i am able to tweak a little more but i am running two 5970's getting 1.26mh/s Ltc solo mining. 3 days and no block found yet 
i let this run the other day on btc for about 5 hours and made .03 of a coin
0-1 has an aftermarket cooler
2-3 has stock cooler.
Lol... man Solomining isnt going to be worth it until 10Mh/s ... You have a few rigs to build until you get there... do Notroll or other litecoinpools...i let this run the other day on btc for about 5 hours and made .03 of a coin
