Service Pack 3

I've heard that people get some problems with SP3, but yeah it's what I heard. I'm going to try to avoid getting it unless it's really necessary for me. Don't need to fix what's not broken, right?

Well...that's if it isn't broken to begin with...but I guess if you're not having any problems with your SP2 then w/e you decide. Apparently SP3 gives a 10% performance boost :S.

I did hear people having problems with the Vista SP1, some people had problems with SP3 but I think they were the RCs and they're fixed now.
