I'm not sure what this means or what a GPU even is. Should I put yes or no?

Also, how long do tasks generally take to complete? The 3 I have now will take about 50 hours assuming the "remaining" time left is accurate.

I'm not going to keep my computer on until the tasks finish. Does that mean I should answer yes to this question: Leave tasks in memory while suspended?

I'd put "no", even though, since you're using the default apps and there are no apps for ATI cards, you won't be doing any GPU work. If, later on, you want to switch to the optimised apps, you'll be ready.

You have Astropulse units to work on; these take longer than regular workunits. Don't put alot of stock in the "estimated time remaining" counters. These are new workunits, and there isn't alot of anecdotal data out yet, but 24-36 hours might be expected on the stock app; perhaps longer on slower machines.

Before you turn off your computer, be sure to exit BOINC. When you restart again, make sure BOINC has restarted; that usually happens automatically. Your jobs will restart from the last checkpoint. There is no need to leave the tasks in memory.

Thanks. One more question; If I'm running more than one program on BOINC will it slow everything down?

Which programs would you recommend?

By program, you mean different projects? No, it won't affect speed. BOINC will switch automatically bewtween different projects so that each gets its share of your available resources. Of course, different projects' work might utilize resources differently (more or less memory, or I/O, for instance) so that might affect your system's performance on non-BOINC uses, but if that happens, you can suspend BOINC.

There are a number of settings that can impact how and when BOINC uses your system. Once you've gotten used to running it for awhile, and have an idea how it affects your system, you can start fine tuning things.

As to other projects, look at this list and pick something thst interests you.

yes I meant projects. What I meant was, if I have 7 projects going, is each individual project going to get less done than it otherwise would have? Like if I just had seti@home running by itself, would it be more productive than if it had 6 other projects?

I'm assuming yes it would get less done the more projects i have running...

It will get less done for each project, but may very well get more done in total. Most projects have outages (either intentional or not) that can be covered by work from other projects.

For example, SETI@Home has regularly scheduled outages on Tuesdays that have a tail that last for a day or two where it is hard to get work. S@H also runs on a shoe string budget and occasionally has a hardware failure where the project goes down for several days to several weeks.
