Are you going to duplicate the data?

If you are going to have 3000 sql statements per second, I would suggest,

1. Get quad CPU. You probably need that horsepower
2. Use prepared statements and stored procedures to avoid parsing overhead.

I doubt you would need cluster of machines though. If you run it thr. a pilot
program, that would give you an idea whether or not you need a cluster..
