Definitely get a PC. I have a dell I bought last year. It makes streaming a breeze. In my experience laptops run slow for camming and are just not equiped to do everything like a PC can.
These are the tech requirements for LiveJasmin. At the time of purchasing my pc I was working with them so I used this as a guide. Streaming has been flawless unless the site itself has issues
Hope it provides some insight as to what to look for.
