Integrated AMD Radeon??R7/R5 Series Graphics in A-

The answer to that question is fairly complicated and depends on a number of factors.

Thanks PetrolHead for the additional info . I just realized I should have said: 

Two things should be pointed out:

1. AMD APUs have the same issue as the FX-series, which is that the cores are "marketing cores". The amount of "real" cores depends on the application. In some applications you in practice need to divide the number of cores by two due to there being only one floating point unit in each "two core" module; in others the CPU functions like a four core CPU would.

2. The amount of cores is not the only factor. You also need to consider how fast each core is. The single threaded performance of AMD CPUs (APU or not) is way behind modern Intel CPUs and in applications where the software can't take advantage of more than two threads a simple i3 will likely wipe the floor with any A8 APU.

Not that the A8 CPUs are useless, but you should not think of a CPU just in terms of cores, since it means different things in Intel and AMD CPUs and it's only part of the story.

In any case, it all comes down to what you're playing and what sort of performance you'll expect. Modern AAA titles are not really designed to be played on budget systems, but lowering the resolution and detail settings should make them playable just like Xaltar said. MOBAs and possibly older AAA titles should not be a problem for your system.

4 cores should is fine. Everyone always goes on about minimum this and essential that but at the end of they day if all you are looking to do is play AAA titles at decent frame rates with acceptable quality levels you don't need anywhere near the specs most forums will try and tell you.

Well, i really want to play those AAA titles but they cost much. Ill just gonna focus on my hardware for now and try some later. Is a8 good enough for gaming? Cos they have 4 cores. How much cpu cores do I need for a good gaming experience? Youve been helping me a lot, i really appreciate your effort answering my questions. Thanks.
