Final Cut X compatibility with early 2008 iMac
iMac, OS X Yosemite (10.10.3)
It meets the minimum specs. Depending on the kind of projects you have, you may have a decent working experience – or not.
The best way to tell is to download the trial version and work with actual media in projects, If it's satisfactory, you should look into more RAM.
Good luck.

Thanks, Russ. I'll give the trial version a whirl!
