Best gaming (performance) laptop under 1500$ CAD?

So I live in Canada and I'm looking for a laptop that's under my budget. A little over might not be bad, but it definitely needs to stay in my range. I'll be using it for Photoshop, Inventor, Revit, and some other programs as well as gaming. I was looking at the Lenovo Ideapad y510p which didn't look so bad. If anyone has other suggestions please let me know. Oh and some info that might be useful for you: I'll almost always be plugged in, but I still need to be a bit portable so battery isn't an issue. I'd prefer if it was a 17" laptop.
Cheers!
