GC was great my old Pent 3, 1 Ghz 512 MB box Outputing a good chunk of results a day.. over 10 a day..
Switched it to HPF-P2 for now only since it seems to be less heavy at times then FAAH Work Units.. I hope there will be more GC work in the future it is fast and fun and I am sure many other members used it to capitalize on results score. I am waiting for more work like everyone else.. but as long as the current work is available and my systems are not idle all is good.. I personally wouldn't use any system less then 1 Ghz. for any Grid project out there.. the power consumed based on system output would be too great to put time in.. I agree tho with the GC project and a 466 Mhz system still pushes out a good amount of results for the setup.. always when new projects come out.. I see how they run and adjust them to work on the right system. I know the Cancer one is going to take some good horse power RAM wise. not a issue with 4 GB on one rig and the other stuck with 512 MB due to BIOS limits.. got a old laptop with 1 GB of RAM.. I could use that but it runs hot I would need to get a chill zone for it first.. hope there is something you can crunch with us soon..

Here's what I am connected to myself. Some of these are as intense or more than here. The projects that I have highlighted all have small workunits. Due to changes, others may or may not work. There's no graphics, though on some of them.
Dependency Spider is a special case, and can run in PARALLEL with this or any other BOINC project, rather like DIMES. It checks internet sites while you are online, but doesn't take much % of the computer.

Not all projects have work all of the time. You may have to hook up to more than one. In the advanced BOINC view go to Tools, attach to project, and enter a URL in the box. Register. Join a team. There is a Vulture Central Team at all of these, so I've been there. A few, like one of the climate projects may be closed by now, but you never know. Some have never even gotten started, and there are a few more not on this list that cannot even be connected to and registered.

I just finished a 2.5 minute Chess960 workunit on the fast computer while I was writing this, so you should be able to kick one of those out in 10-20 minutes, I would think.

Hopefully, we will have something useful for you here now and then, especially if GC sends us anything else to play with.

This project has very tiny download/upload files, so is good for dialup users with metered traffic quota.

Thanks retsof for the extensive list. I'll peruse that for some medical related projects if my slower machines can't cut the muster.
