I see you have both an nVidia and an AMD graphics card. Ever considered crunching with those? Your ATI card could get 200,000 credits per day on MooWrapper if you are interested. If you prefer space science, MilkyWay@Home is another good option. Collatz may be the best option for the nVidia 9600 GS, but it would also get at least 1K per day. If you have any question on how to get those GPUs crunching, just ask!
