Just adding to Set's suggestion.

Pretty much any server could handle 1000 inserts per second. My laptop
manages nearly 10000 per second running on batteries.

You mention you have a few nasty queries. It would be wise to spend
your resources trying to optimise the statements to take the nasty
edge off them. If this is not possible, then you could backup the
database and restore it to a different server and run your nasty
queries on that server.

As far as Classic or Superserver, since you have quite a good budget,
I would go for a SMP machine with Classic Server.
