I appreciate your comment @jamezz! Some more clarifications from my side: idea is not to get rich with Gridcoin, maybe to pay a small portion of the electricity bill. I do not discourage people to run one project or another, but we have plenty of interesting projects, and some of them can not be computed by GPUs (either the software is not properly developed, or the algorithms are not suitable for huge parallel computing). GPUs are very good at processing Seti@Home, therefore I recommend people to let them for GPUs and put their CPUs on projects that are not running on GPUs, and would really appreciate some additional CPUs to crunch their data.
