The A10 5757m as stated in your post only has 8650g graphics, which is where it's really weak. These AMD APUs can and often do have more powerful built-in graphics than Intel CPUs, but for gaming they are best as a supplement to a dedicated graphics card, and they only work with cards up to a certain power. With a laptop it also has to be the type that will accept a dedicated video card before you can even do that, and LT graphics cards are not cheap.
Here's the raw graphics power of your APU to give you an idea, and note that I've seen guys with 765m Nvidia based laptops that have over 2000 point scores on Passmark struggle to play modern games like AC IV on ANY settings without huge lag.

The other problem you face with LTs these days is a lot of game devs refuse to do play test support for them, so you're taking your chances on compatibility and driver issues. Of course I'm only guessing about gaming. You really have to give us some idea of intended use before we can judge it's effectiveness.
Ultimately it depends what you want to do with it and what games if any you want to play and at what res and settings. I HAVE seen YT vids claiming to be able to run BF3 and Bio Infinite on pretty much the same spec, but the Bio Inf one had a dedicated graphics card in it along with the APU so I didn't post it, and I'm skeptical that the BF3 vid may have had a similar setup, despite not saying so.
My advice if you insist on going the LT route is get one that you can add a dedicated graphics card to if need be, and never game with it directly touching your lap, bed, couch etc. Put a proper laptop cooler under it. They're cheap insurance against meltdowns.
