maxing out a 580 is easy though.

I have a 60 GB vertex 3.

55.7 GB available to windows. 35.8 GB in use, 19.9 free with windows 7 ultimate with a few features trimmed, hibernate disabled, 8 gb page file and BF3.

BF3 being 11.4 GB.

Could install skyrim on it but its not worth it. Loading screens are so brief I can't finish reading some of them.
