Large databases / performance

I have placed all my tables for a website into one database - including vBulletin and all my custom stuff. I was checking the other day and my database is now up to 8.5gb. I have 162 tables, but some are "backups" of other tables, some of those backups are themselves very large (couple million records each).

So, my question is does overall size of a database impact performance or is it strictly individual tables? Does having backups of tables in the same database adversely affect performance in any way and should those be moved to a backup database of their own?

Just curious - if you know of good reference material, am trying to understand how database size can impact MySQL performance as our site continues to grow.

It is not a VB3 engine, just a parsed copy!
