intel i5 8400 vs i5 7600k vs i5 7640x

I am wondering if any of you cpu experts know a lot about these cpus and can tell me how good they are, and how they stack up to each other. my main purpose is going to be 4k gaming. 

 

Intel i5 8400- $200

Intel i5 7600k- $230

Intel i5 7640x- $230

My opinion is that there is no point in going for older gen cpus. 8400 is the best put of these as it is 6 core. You wont have any problem running 4k. Just put money into the gpu.

Go for the i5 8400 or you might be interested in looking into the r5 2600.

 

The 7600k is just bad value and from an older plattform not worth investing in.

 

I5 7640x  is not worth any of the money. Its the worst choice on the list.

 

In 4K gaming the GPU will allways be the bottleneck. You can probably grab an r5 2600 and a B450 motherboard. And then if you want you can upgrade on the same mobo later on

i5 7640x is gross, 7600k is a boring quad-core and 8400 is only decent choice of what's shown. Considering 4k doesn't care about AMD vs Intel, a higher core count from AMD might be the better option.

If you don't have a mobo yet, I would go with AMD, especially at 4K.

I'd probably have to suggest Ryzen as well (even though I almost always suggest Intel for gaming) since you want to play at 4K. Something like a 2600 or 2600X.

 

It's not that Ryzen is better at that resolution, it's that your CPU choice doesn't really matter at 4K and you might as well get more threads for your money for any other work you want to do on that PC. The 2600(X) does offer notably better multithreaded performance than the i5-8400 due to having twice as many threads.

 

I'd recommend the MSI B450 Tomahawk if you choose Ryzen. That motherboard is a friggin' tank. Insanely good VRM temps even with an overclocked Ryzen 7 2700.
