For now I think I'll stick with Boinc projects. I have one GTX260 on GPUGrid slowly bring it up to 25,000,000. I have three HD4850s (2 full time and 1 part time) on Milkyway to get it to 50,000,000. The rest, nine GTX260s and two HD4890s are on Collatz with no set goal except to make as much credit as possible.
