Hey All, So I BTO the 460, but received defective OTA, so I am going to return it tomorrow, since it is BTO, it will not be stocked, so now I have two choices: 1.Get the 455 in stock 2.Order again the 460 and wait for 2-3 weeks. I do light photoshop and light room, I mainly do web dev, app dev, not 3D, and for other regular office works, like PPT, excel, word...etc. And I sometime to RDP to my windows servers, but rarely. So will the 455 be enough for my situation, plan to keep it for 3 - 4 years. Any advices? Thank you all!
