Which hp laptop is best for a graphic design/gamer?

I believe that HP envy should be a good choice. You can check out the different variations of HP from the Below Link. http://www.shopping.hp.com/en_US/home-office/-/products/Laptops/Laptops;pgid=c7twGfjc0ptSRpIq7ZUcoGXQ0000ESUiq2UB;sid=prFRidVD4Nfym4QI53b5AQ1MrGrcIuFfY-QVSiDWrGrcIhMyK4S-CGND?SearchParameter=%26%40QueryTerm%3D*%26categoryusagelaptops_dte2%3DHigh%2BPerformance%26CategoryUUIDLevelX%3DjeEQxXjbj14AAAE0syxcZzOW%26%40Sort.TieredPricing%3D0&PageSize=15

HP, and most other Laptop manufacturers have numerous models of laptops with slight variations of configurations and features at various price points. It is difficult to point to a single laptop and call it the best, and in case of most models the model nomenclature will be something cryptic that will not really be helpful to know. I suggest you fix in mind a budget you are willing to shell out, then search for the models that fit in that budget, having a good processor, RAM and a discrete GPU. An i7 won't really give you any performance gains in most games, but is pretty much mandatory for serious graphic designing work, as is atleast 16GB of RAM. Having an SSD will also help your workflow.
