@havanesefluff - Between a MacBook Air having much weaker hardware (they are meant to be lightweight and portable, not really for heavy game programs) and the Mac version of the game being crippled as it can only utilize 2 GB of RAM unlike its Windows counterpart that can use almost twice that, you're already looking way ahead of where you are now and the Inspiron linked to will provide a much better experience.
Laptops with dedicated cards of sufficient strength will run higher, but your budget should allow for something better than integrated graphics only. Calling in someone with more finely tuned shopping skills. :)
