No I guess not....lol.
Seriously though, this 7077 build is rock solid in terms of reliability. I set my machine up the other week, applying an overclock to 3.5GHz (actually nearer 3.6 but anyway) and then ran Prime95 for two hours without error.. Since then, I don't think it's locked up once nor done anything weird like vista used to do..
The RC is supposed to be out in the next two weeks (May 5th I think) and that build is supposed to be numbered '7100' but I guess time will tell....
