I'm using 7 home, but I found out at christmas, after receiving more memory, that windows 7 home can only use 8 gigs. I've been having out of memory crashes running 5 rifts a LOT now, so it might be time to bite the bullet and upgrade. Are there any pitfalls I might not be aware of?

I multibox Rift and Wow and might be trying non-boxed FFXIV later this week.
