While I would recommend a desktop instead of a laptop for gaming, if you must have a laptop then I strongly recommend something with more graphics horsepower than the A10 APU-powered system you were considering. I feel shifting away from AMD APU (with or without a discrete GPU) to an Intel CPU + nVIDIA GPU would offer a much better and more satisfying gaming performance.
$700 is a little more than enough to cover a system equipped with an i5 and GT 940M GPU, but a little more money can net you a GTX 950M. And anything less than the performance level of a GTX 950M is very likely going to yield underwhelming gaming performance on today's newer games, let alone tomorrow's upcoming titles.
Newegg had
this GTX 950M-equipped MSI GP60 Leopard on sale for $690 a few days ago as a Shell Shocker deal, so we may see a similar price again. For now, it's back to nearly $800.
I prefer searching for nVIDIA-equipped laptops through nVIDIA's site, though. Go here:
http/www.nvidia.com/object/notebooks.html and click the desired the GPU, then on the new page select Buy Laptop to see a list of laptops being sold through some of the most popular online stores. It isn't updated quite often enough, but it provides direct access to laptops equipped with the GPU selection at different vendors.
I, too, have been contemplating buying a multi-purpose laptop that I will also game on regularly. After researching mobile GPU gaming performance, I will eventually be going with something that has an Intel Core-i7 and a GTX 960M or better, and I fully expect to pay $1000 to $1400 for such a system. I've been wading through a lot of "Back to School" promotions recently and just haven't found a must-have offer, yet. Even this
$900 Acer V15 Nitro hasn't given me that feeling. At $900, it offers powerful hardware for the money and an excellent screen, but I dislike its underwhelming internal cooling effectiveness, complicated upgrade installations, and the fact that every single port is packed into only one side of it.
