http://cpuboss.com/cpus/Intel-Core-i5-2500-vs-AMD-A10-8700P shows that the processor in yours is limited, (Compared to what I ran B3 on) that being said B3 should be able to run on it, but you'd have to make sure turbo is on.
My concern would be your graphics - using the Radeon R6 M255DX comparison:
http://gpuboss.com/gpus/Radeon-R6-M255DX-vs-Radeon-HD-3870 to compare with one of the most basic cards that will work on lower resolutions, I think you would be pushing it to run it at more than medium graphics and I wouldn't even try with B4.

I could be wrong, though so give it a shot and let me know how you went.
Game on!

" Medium " and " low ". Don't count on it for graphic settings on " High ".

With no lag at all? Depends where you live and how merciful your internet provider is.

All in One computers are awful for their price points.

Why exactly did you buy that? For that price you could have build an amazing gaming pc. Not saying that it was a terrible purchase, but if you got it mainly for gaming, you could have gotten a way better pc.

Should probably do Medium just about, especially if you drop the resolution, might be a few nasty FPS drops here and there. It's like any lowend laptop graphics tbh, start at low and take everything else you can get away with as a win.

Will say though if you bought it new/can still return it and can hold off a couple of months Bristol Ridge is coming imminently, so you should be able to get something significantly gruntier for a similar price (infact that seems super expensive, but maybe that's just Australia?).

it'll run fine but in my opinion battlefield 3+4 are a huge letdown, if you like shooters I'd rather go with games like farcry3+4, wolfenstein new order, gta v, just cause 3 maybe even payday2 but hey that's just me

It can run BF3 on Low around 40 FPS at best. Sorry.

is this a troll? OP are you 12? did you just pick an 1800$ pc because... its expensive?

The A10s are low-mid gaming APUs. You can run any semi-recent game with acceptable performance at low-mid settings and 720p (maybe 1080p) on it, and that's it.

wow that is an awfull prebuiild, i hope that money is not american dollars, because if it is then your getting ripped off.

oh is australian dollars, well those games have been out for quite some time, so it should be fine ish for those games.
