Wow, something is seriously wrong. Just one of those cores should  
handle the job with ease.

Are you running any other CPU-hungry apps? If not perhaps your video  
driver setup isn't optimum, assuming that's an AGP video card.

Are you sure you're clocking the CPU where it should be? Frequency  
scaling might be set up wrong, or the mobo settings?

I'd try and figure out what's going on because even if it's working  
OK for you something isn't right and it may bite you when you least  
expect it.
