<p>Don't bother GPU mining, especially for SHA-256 (bitcoin). You can blow one of those out of the water with a $20 used USB ASIC on ebay. The days of casual mining are over, you will be operating at a loss unless you have some of the cheapest electricity in the world and a large mining setup. </p>
