It is possible to crossfire the A6-5400k with a gpu like the R7-240? Also, would it be good enough to play BF4 with graphics set to medium?

Bottleneck is an easy misconception. Your CPU handles the game engine. The CPU is capable of a certain amount of FPS depending on the game engine code and how fast the CPU is. The GPU is going to handle resolution, pixel shading, post effects, ect, and depending on the resolution and settings, a GPU will be capable of certain FPS.

In summary: You pick your CPU depending on the game engine. You pick your GPU depending on the detail settings.

A lot of newer games will utilize more than two cores, so in especially those games your CPU will suffer. A vast majority of the existing catalog of all games only needs 1-2 CPU cores though, so your CPU will be fine for those.

Thank you for your answer, I think I'll be better buying something more powerful like a R9-260 or R9-270, tought would my cpu bottleneck it?

I would get a more powerful GPU like the R9-270, and save up for a quad-core upgrade. Soon enough Kaveri based NPUs will be coming out. At least you will be pushing higher detail settings even in games where your CPU is a genuine bottleneck.

Thanks! I'll keep that in mind, I'll first upgrade for a R9-270 and will later (in the following years) be buying a new cpu/mobo. I was thinking about a i5 or maybe a i7 but it will depend if AMD release new cpus that arent apu.
