It takes a little less than a minute on my system which is Athlon 2500+ O/C'd to 3200+, 512 MB RAM, and a WD Raptor 10K RPM SATA HDD. There are a couple of things that slow that down, such as RAID boot screens, hardware profile selection, and memory virus scan, but it's pretty decent. Windows is configured to automatically enter my password, and it takes about 2 seconds to go from the welcome screen to completely booted (I tweaked my services.)
