Eh . . . I'm not so sure about the latest game releases, but if you're up for games released in the relatively recent past then I'd check out MSI. I've had better performance on my laptop from them than I've had with the tower from Dell (both of them are intended for gaming). MSI from my very brief experience (one purchase) has served well, but there are surely other laptop rigs that out-perform the one I have (GP60 2PE Leopard).
My laptop was around $729 off of amazon: I settled for this
http://www.msi.com/product/nb/GP60-2PE- ... o-overview product, which was a brand new purchase. I didn't like windows 8.1 so much and struggled with determining whether or not I'd downgrade, but after running a little trial with games like TES: Oblivion, NBA 2k11, The Sims 3, Just Cause 2, etc I was convinced I could tolerate the user interface (after installing classic shell and customizing to my preferences).
Now I've never purchased from them, but when I asked someone on a different forum (dedicated to a particular game) they directed me to this website:
http://www.ibuypower.com/ among others which I have forgotten, but seeing as their prices can fluctuate it's something to keep an eye on.
