Do you *absolutely* need 1000 updates per second?  What are you doing that 
requires such precise timing?

Keep in mind that even though you're using multiple threads, your code won't 
run any faster.  You've still got the same amount of processing power.  So 
if your logic loop can't keep up with the graphics in a single-threaded 
program, it won't be able to in a multi-threaded program either.  What you'd 
basically end up doing is having the graphics thread wait for the logic 
thread to finish its update, and they'd operate in lock step - at which 
point you're doing pretty much the same thing as having a single-threaded 
program.
