Are you sure you REALLY want one of the first 2012 iMacs to roll off the line?
As a mechanical engineer with almost 30 yrs experience, and considering the mfg. problem delays, I'm hesitant.
I agree with waiting for a little bit. But my reason maybe a little different than others.
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 with 8MB L3 cache
8GB Ram, Upgrade to 32GB 1600MHz DDR3 from OWC or Crucial
1TB 7200rpm Fusion Drive, or 768GB SSD with an External Thunderbolt Drive.
NVIDIA GeForce GTX 680MX Graphic processor with 2GB of GDDR5 memory
AppleCare Protection Plan
Samsung SE-506AB Slim Portable Blu-ray Writer
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. (Note - 3TB drives can't currently be partitioned for Bootcamp.) and I rather use Bootcamp. I am confused as to what Drive setup I should get?
Now we get to the reason why I might wait before I get my Imac. Maybe OWC has looked into doing Turnkey with the New Imac's and Install Larger SSD [256GB or 512GB with a fast 1T HDD or 4T] with or without the Fusion part? Not knowing if the IMAC 27" Drive bay will even accept them? Here’s Hoping.
Apple may even fix Bootcamp to work with 3T HDD and Fusion 3T. But would be even better is for them to give upgrades of 256GB or 512GB ssd with the Fusion Drive. So this is the reason I might wait.
