Help with partitioning scheme for new build

[grizzed]

I'm putting together a new desktop and will be trying to make a full time switch to linux. My hardware is on the way and I'm looking for some insight as to a partitioning scheme. I'm getting my feet wet and will probably rebuild the OS structure next year - maybe to ubuntu 14.04 hopefully to SteamOS.
system use: Gaming - video/photo editing - browsing - gaming - gaming

Primary OS - ubuntu 12.04
Alt OS - STEAMOS & other debian flavors - mintOS - (no windows!)
RAM - 16GB
Drives

• SSD 128GB
• WD black - 1TB
• WD Green - 3TB

I'm looking at 3 types of partitions

• OS partitions
• Dedicated primary OS partitions (used ONLY by ubuntu 12.04)
• Shared partitions that can be used by all the (debian) OS

OS partitions

• ubuntu 12.04 25GB on SSD
• ubuntu studio 30GB on SSD
• steamos 25GB on SSD
• mythbuntu/mint 15GB on SSD

Shared partitions

• swap 16GB on HDD black drive (for hibernate)
• /boot 1GB on SSD
• /tmp 10GB on HDD green drive 8
• /export 400GB on HDD green
• /media 1024GB on HDD green

Primary OS(12.04) dedicated paritions

• /usr 10GB on SSD
• /opt 5GB on SSH
• /var 15GB on green HDD
• /home 400GB on green HDD
• /home/beans/steam 1000GB on HDD black
• /home/beans/.wine 30GB on HDD black

With 16 GB ram I'm thinking I won't use swap much and putting it on the faster HDD will allow for fewer writes to SSD and still let me use hibernate.
The same applies for /var on the slower SSD. There's plenty of RAM for log messages until it's got time to write to the HDD.

Any help/suggestions is appreciated.
