I'm sorry. Did you say a GPU miner for SHA256? 
You will go bankrupt just trying to generate a valid share on probably any mining pool using a GPU for that.
GPU < 1GHS
ASIC > 10,000 GHS
Right there. Unless your GPU costs less than about $1, and your electricity is free, I would advise you to replan your strategy.
