Best $400 laptop?

[BWillie]

I need to buy a new laptop in the next week. I dont care if its refurbished, would almost prefer it. It needs to be able to have a fast hard drive to access data extremely quickly and preferrably a quadcore. Higher resolution the better. Also need to be able to plug into a monitor but i think any of them should be able to do. Is there a big difference between a hard drive that us 7200 rpm vs 5000 rpm? I have. A ssd HD on my main computer i use to play poker on and its absolutely fantastic.
