Hello everybody,

I have a Dell Latitude E6430, which I use it mainly as a "portable" gaming device with an eGPU. It has an i5-3340M on board (2.70 GHz - 3.4Ghz turbo) and 8GB DDR3 RAM. I have the possibility to cheaply upgrade it to i7-3740QM with around 55 dollars. Is it worth it? Does CPU play that of an important role in gaming? I am using the laptop with a GTX 660 Ti I haven't gamed so much with it but will I see an improvement or not?

I read many posts regarding the importance of CPU in gaming and I am totally confused.

Thanks in advance for all the answers!

There articles may help, in general it depends on your use case:

also read the bottlenecking guide: http://www.tomshardware.co.uk/forum/id-3192807/ultimate-bottlenecking-guide.html
If you want anything stronger than a 1060 the cpu can become a bottleneck. Regarding the core count, i7-3740QM would be a beneficial upgrade, otherwise not a must.

I don't think you can swap out those CPU's. Most of the time they are soldered. Specially with Dell. Do you think Dell would allow you to upgrade a laptop CPU? Highly unlikely. Then no-one would buy there new laptops!

To answer your other question, CPU's can certainly play apart in gaming FPS. But it's the GPU that's the primary driver of fps. Having a fast CPU will generally push out an extra 5-10% fps at certain resolutions from a powerful GPU. But this game dependent an not across the board.

Thank you I will check it out. I know about bottlenecking the thing that I do not now is how important is the CPU in this case.

Using a GTX 660 Ti the CPU is no bottleneck. About core counts and gaming here is a fresh article : https://uk.hardware.info/reviews/8463/how-many-cpu-cores-do-you-need-for-gaming
