Optimal Graphics Card configuration to also work with FCP X

Hi all,

I'm looking to upgrade my graphics card to accelerate CS 6 as well as FCP X. CS 6 seems to only like Nvidia cards that support CUDA, and FCP seems to benefit best from the 5870.

Does anyone out there have a machine that's running CS 6 and FCP X and benchmarked a card that works great for both?

My machine:
Early 2009 Mac Pro
32 GB RAM
512 GB SSD Mountain Lion Boot Drive
9TB Internal RAID array
NVIDIA GeForce GT 120 (x2)

Carlos,
Any answer to your question? I too want to set up a Mac Pro (early 2008). I want to add 1 internal drive for Adobe Premiere and 1 internal drive for FCP X.
Do they both need OS Mt. Lion?
Can they both use the same graphics card as you ask? Currently I have NVIDIA GeForce 8800 GT installed. I can add the Quadro 4000??
What about legacy productions edited on FCP 6.06 will they open on a new graphics card and in OS Mt. Lion?? For example, I was just asked to do a re-edit on a past production edited in FCP 6.06.

Any thoughts and suggestions are appreciated.

Peace, Huey
