Yes.

I have a Mac Pro 2006, MacPro1,1 my video card does not support the new Final Cut program

lots of threads since FCP-X came out and 1,1 owners.

answer you probably need a new GPU unless you have already bought this ATI Radeon 5770 or Nvidia 8800GT

Apple has:

Final Cut Pro X, Motion 5, Compressor 4: Graphics card compatibility

GTX 570 can also work if you look around. Check ebay or MacRumors for "MacVidCards" that supplies and supports graphic card options.

One question, the Final Cut Pro X system requrements say you need:  "Mac computer with an Intel Core 2 Duo processor or better."  I talked with Apple, and they weren't sure the Dual Core Intel Xeons met the requirement.  If they do, looks like an ATI HD 5770 solves our problem!  Can anyone confirm the Xeons will work with Final Cut Pro X?

Charlie Brown moment: All Mac Pro have Xeon 64bit and meet the requirements.

Did you actually read the replies?

Haha, the "genius" I spoke to at the Apple store said only the really early versions of the 2006 models had Xeons, the rest had Core 2 Duo's.  He made it seem like I was basically using a G4.    It's what I get for not doing the research myself.  Thanks again for the answers!

Apple trains their support people on what is currently for sale in the stores. Their knowledge of older systems is wildly variable.

If they had extra time to take a class, it would more likely be in "how to satisfy customers" than "antique computer specs".
