hi Folks

I have MacPro 3,1 Quad-Core Intel Xeon with 32GB ram. I fear the machine is bottlenecking at the GeForce 8800GT card with 512mb memory. Id like to upgrade the card to AMD Radeon HD 7950 3GB.

When I bought the machine it came with 10.7... Adobe Creative Suite Cs6 and Final Cut Pro Suite (FCP7) were getting errors and I was advised to downgrade to 10.6 which I did. Now the programs work ok but the computer is so slow, even with dual quads (8 cores) and 32GB ram.

So to upgrade the card, I understand it needs at least 10.7.. Im wondering if there is a benefit to upgrade the OS to like 10.9

1) is this even possible in the computer and
2) will these suites still work with upgraded OS and this card?

Could anyone shed some light on this for me before I drop near 400.00 on a card? thanks.

Phil
