Higher usually means like 2.4, 2.6, 2.8, 3.0 gHz... if your going to be doing multimedia work I would go for a new Motherboard and at least dual core CPU... you can usuall find an older model on newegg for around $100... I paid $110 for my mobo 3 years ago and have an AMD X2 2.8gHz processor... so if you can spend the money that would be the best option I think... but if you are just wanting the new processor... then getting a faster P4 would do the trick.... as close to 3.0gHz if possible... I havn't found if there is a limit on your MOBO but based on what you found... you should be ok with a faster P4.
