Luke if your budget can handle $900, here's a very good laptop that runs Windows 8.1 64bit with 8GB of ram, 1TB hard drive, an Intel Core i7 processor, and an Nvideo GTX950M video card, which Premiere will love. http://amzn.com/B00TCULFJ4
I have a similar model, and while it's not as robust as my desktop, it runs all the Adobe software quite nicely. As a bonus, the laptop will get a free upgrade to Windows 10.
