I'm a little hesitant to recommend Acer but the
Acer E5-771G-51T2 is probably going to provide the best "bang-for-buck". At 17" with a dedicated GT840M graphics card, Core i5 CPU, 1TB HDD, and 8 GB of ram, it's pretty well packed.
The drawbacks? It's big, it's a 17" laptop, at 6.6lbs, it's not the lightest either.
As far as my hesitation to recommend an Acer, as I point out, big bang-for-buck value but I've had issues with Acer laptops in the past. I will readily admit that I took very little care of those laptops so the issue may not be completely Acer's fault but when two die within 6 months of warranty expiring, well... I tend to keep clear personally anymore. One was a simple fix I just didn't want to deal with.
