Can Bootcamp 4.0 be used on either 3T HHD or The Fusion 3T HDD

I am planning to get a NEW 27" IMAC [if they ever come out] and use Bootcamp or Parallels Desktop® 8 for Gamming.

I work with Photoshop, and Adobe Premier, After Effects and I play WoW on MAC and Star Wars Old Republic and other PC only games. I have a Synology DS212+ NAS for Data and Backup.

Going with:

27" 3.4GHz quad-core Intel Core i7 (Turbo Boost up to 3.9GHz) with 8MB L3 cache

Upgrade to 32GB 1600MHz DDR3 from OWC or Crucial

3TB 7200rpm Fusion Drive Maybe

NVIDIA GeForce GTX 680MX Graphic processor with 2GB of GDDR5 memory

AppleCare Protection Plan

Samsung SE-506AB Slim Portable Blu-ray Writer

As you see I was planning to get the 3TB 7200rpm Fusion Drive.

Choices of drive 768GB SSD, 1T or 3T Fusion HHD, 1T or 3T HDD

The problem is with Bootcamp you need to partition your drive. You don't need a whole new drive and I rather use Bootcamp. I am confused as to what Drive setup I should get? Do you have any Ideas on the matter?

There must be a number of Gamers that are in the same quandary.
