    Is this Notebook's CPU a bottleneck?

    The laptop seems great but the cpu seems worrying to me.

    AMD A10 5750m 2,5-3,5
    8gb ram
    750gb 7200rpm
    17 inch 1920x1080
    8970m

    What games are more CPU orientated?

    A huge bottleneck. Topic has been beaten to death. Don't get it, unless you enjoy seeing your 8970M achieve half of its true performance.

    Yes, overall it tends to be a bottkeneck. Get a Intel, to go with the 8970m. As said, this has been mentioned many times on here.

    Yes it is a bottleneck for games, specially those that depend upon CPU power. Games that depend on clock cycle, or are less of a burden on CPU are not much of a problem for it. The GX series are gaming laptops on a budget, but if you really want a strong gaming performance, you are better off with higher end machines.

    An oveclocked GTX 770m+i7 will serve you better gaming performance than the GX, due to the bottleneck.

    Examples of CPU bound games include MMOs , RTS like StarCraft II, total war games etc.

    I had one ordered, got cold feet and went with the i7/765m setup.

    The problem with the bottleneck is, lowering the resolution qualities doesn't help until you down to point where the cpu can catch up. With an i5/7 you can lower the quality and get a significant jump in fps, so in a sense, more "futureproof".

    Don't forget Skyrim, Borderlands 2 and most UE3 games, and the most CPU-hungry of them all, Battlefield.

    Games that are well multi-threaded or primarily GPU-bound aren't going to suffer as much because of the APU. Games that are single-threaded or depend a lot on IPC and per-core efficiency will run much better on an Intel. Of course then there are games like Battlefield that need not just lots of cores but very fast ones as well.

    Actually, lowering resolution can have the opposite effect when you have a CPU bottleneck. Performance may improve little or even decrease since you are actually making the game more CPU-bound. Increasing resolution and graphics settings such as antialiasing shifts more of the load back to the GPU which could alleviate the CPU bottleneck somewhat.

    This notebook is in a completely different price segment to an Intel + 8970M. He would have to settle for a worse GPU.

    But at this price point he can still get a system with an i7 and a GTX 765M, with luck even a 770M , which will both perform better overall than the MSI GX.

    CPU is weak and low-powered, even though the GPU is very powerful but you will be limited from playing a lot of good games at good quality.

    That's true. I was just pointing out for the OP that it isn't as simple as just looking at a different CPU as those kinds of configs aren't in the same price range, he'd have to look for a different setup altogether. A i7 with a 770M would be very nice

    The GX60/70 has the potential to perform well above its price range in GPU limited scenarios, but unfortunately there are ALOT of CPU bound titles (entire genres), contrary to what people sometimes say about how gaming is all about the GPU. It most definitely isn't that simple

    Mantle will probably make BF4 one of it's stronger titles as its designed to reduce CPU overhead amongst other things

    Mantle will definitely help remove some of the CPU bound issues of games with lower end AMD CPUs, but such technology sadly has just begun and only BF4 so far uses it.

    If it's widely accepted/used, then GX will most likely enjoy a longer lifespan when gaming :D And yeah the trick with these GX series is the price range. While an i7+770m might be a better way to go, it is still slightly more expensive.

    Maybe an i5+770m could do the trick, but that setup would probably have its issues in a game or two :p
