I did find the Beta version was a bit Memory hungry, I think because the reporting aspect took up a lot of Memory
After an initial few days, I reverted back to 10.9.2, waiting for this Official Release
Up to 5.3GB for the basic update, less depending on individual Apple Computer configuration.
Mine here appears to be only a 460mb download !!

I'm going to try this tonight, as my local (HK) iMacs are busy at the moment, SKYPEing back to the UK, and Video Conversions and Copies of todays' Home Movies, and Photo's, and general catching up with Online News
Tip:
When you tell Mavericks to "Try Tonight", OS X installs available updates between 2 a.m. and 5 a.m.
(I presume this means tomorrow local time, as it's 3am here now !)
Your computer automatically restarts as part of the update process if needed.
The next morning when you log in, your apps and windows re-open just the way you left them.
This way your computer is up to date, and ready to pick up where you left off.

958mb download, estimated 12 minutes @ current 16mb/s (whilst downloading)
I save these, so I don't have to use the Internet, just in case I need to re-apply the update for any reason.
Though, just once a corrupted OSX in many years, giving a display problem.
Update:
Download actually took just 7 minutes !!
