I was looking around at other S@H pages and found some neat information about the upcoming version of Seti@Home Client.
This is a little snipet of the page:
"Because of the extra analysis, processing workunits will take more time than it did with version 2.0x. If the workunits take more than twice as long as they used to, however, please let us know (include information about how you run your client, i.e. do you go to a blank screen immediately, does it run in the background, etc.)."
There is some more information about it here:
