Wish you would reconsider. I run a desk top and lap top commuter do work for World Community Grid they are trying to help humanity. My lap top is a cheap HP with a AMD ^ processor and is about 5 years old. The desk top is nothing fancy either. Any help you could apply would make a difference. Stop worrying about those GPU rigs the projects do not support those type of computers. Plus they do not take away anything from your regular power. Just don't run them 24,7 you would be still be contributing to a good cause.
