Will these specs run most games well?

If I have these specs:
nvidia gtx 1080 8gb vram
intel core i7 2640m 2.8ghz
8gb ram
windows 7 64 bit

I am basiacally wondering if the CPU matters a lot for gaming. Would having a really good GPU(gtx 1080) and a not great CPU(2640m) would still run games well? (New games such as watch dogs 2 , GTA V, Rise of the Tomb Raider...) Or do I have to have a good CPU as well as a good GPU for gaming

And if you could guess about how many fps i would get for the above specs, how many would that be (1080p)?

Thanks

  1. How do you expect to use that old of a laptop CPU with that GPU? No laptop currently will come with that configuration. Or are you planning to buy a mobile GTX 1080 to upgrade to? Because if that's the case, it'll be a waste of $700+ to get that card and upgrade.

    Or if you're somehow expecting to use the laptop CPU with a desktop GPU, I don't even know where to start.
  2. Games like GTAV are pretty CPU intensive so that will be your issue. And how are you mixing a laptop cpu with the 1080.
  3. the gpu you mention is for a desktop pc

    the cpu you mention if for a laptop only

    the only way to put those two to work together is to put in a external gpu case and connect via thunderbolt to the laptop and i doubt that the old cpu will have that port

    please explain more what you have in mind and if you can, share with us the exact model of laptop and exact model of gpu
  4. If you have a current i5 you will be fine for gaming. There is basically no difference between an i7 and i5 for gaming. But if you have a terrible cpu and a great gpu you will still have bad performance because your cpu will bottleneck your gpu and limit its perofmance

    I'm basically using an external video card adapter for my laptop to plug it in. Just say it all works out and those are my specs, would it be able to run big games?
  6. then yes, you will but will not be using the gpu at the maximum, the cpu is a bottleneck here

    if for example that card with other cpu could give you 150fps in a certain game, that cpu could limit you to 80 or perhaps less

    you can use it but won't at the maximum

    also remeber that sometimes those adapters won't work at the maximum speed, if you are using the mini pci express to pci express iirc, that port is limited to 4x or 1x

    it works but not at the maximum of the port

    tell us more about the laptop and the adapter in use
  7. External GPU setups do not work - period.

    You're taking a very powerful GPU and massively crippling it. Not to mention the fact that getting it to work in the first place is a long shot.

    I have a dell precision m6600 with those specs except an nvidia quadro 3000m. I would be using this (http://m.banggood.com/Expresscard-Version-V8_0-EXP-GDC-Beast-Laptop-External-Independent-Video-Card-Dock-p-1009976.html?rmmds=detail-left-hotproducts) and plug it into my express card slot.

    then the express card slot speed limitation mentioned applies here

    if you buy that card, the pci express slot will determine how much information is send to the gpu

    this laptop?



    that gpu will need all 16 lanes from the pci express slot, but if you are using this adapter

    or one similar, it depends on the speed of the mini pci express adapter, usually 1 to 4x

    at best, a quarter of what the gtx 1080 needs to perform the best possible

    in this case you have two bottlenecks, cpu, and pci express slot used

    afik, you can do it, but won't improve much the fps you already have probably
