Does it has to be an overpriced macbook or a top of the line gaming laptop or a PC (you have to build it yourself , i only suggest components , Prebuilt PC cost twice as much) ?
_Macbook Pro Retina 15" (i7 4750M @ 3.0GHz turbo with 4 cores active + Intel HD Iris Pro 5200 which is on par with Nvidia GT 650M) : 2000USD
_Gigabyte Untra Thin Gaming Laptop (i7 4700HQ @ 3.2GHz + Nvidia GTX 760M) or The better version (better cooling unit) (i7 4700MQ @ 3.2GHz + Nvidia GTX 770M) . Both of them cost 1400USD each (also include 128GB SSD)
_A top of the line gaming PC for Dolphin : 600USD+ (Will throw it here if you choose this option)
