I have an 867 MHz. Is there anything I can do to upgrade this, or just getting a new Mac is the solution??

You can replace the graphics card with a Core Image supporting card like the Radeon 9800 Pro, but YouTube and other online video will always be a challenge. People notice some improvement, but online video needs more CPU than GPU.
Should you still desire to upgrade the graphics card, I have a list here:
I'd lean towards a new Mac. You could replace the video card but not likely to show much improvement. I'd agree with japamac that the cpu would still be a challenge with the 867 MHz. I'm on a 3.40 GHz computer right now, I have several computers with less, and on this one it really makes a difference, not only with video on you tube but also the audio music is a tremendous difference.
An alternative solution for the OP would be to download Mactubes. This nifty app has the ability to allow you to play youtube videos(comments not included) in Quicktime format or Video format and of course, Flash.. but why play flash when you can view the videos under Quicktime.
Check on line for mactubes 3.1.5 - Your G4 will be glad you did.
