Anyone have it up and running?

Just finished downloading it but I wonder if it's worth the trouble installing it if the Retail is coming out soon.

I changed out my MB so I've been re-installing OS's for 2 weeks. The Gigabyte EX58 board has been my most difficult project to date. As much as I like 'playing around' I've neglected my honey-dos.

How much different is it than 10A411 (that's the last one that I'm familiar with)?
