Bok,
As you know I'm not the quickest learner on the planet and just wanted to double check I got this right!

I dl'ed the optimized 5.3.1 client for my Athlon 64 from your sticky. I then, just in case, moved the boinc file I already had into a backup folder and dropped your version in where it was and restarted my Boinc manager.

Is that it, almost seems too simple? With just a single 3500+ rig running a gig of ram my RAC score is about 260 - what sort of difference can I expect from this alteration?

Thanks for your time and patience
