Help me choose between i7 8700 or 8700K

 Share

Go to solution Solved by Verrm,

#2 is the best option imo, the 8700k is a great cpu despite not that warm reception of coffee lake as a whole. The 8700k with its 12 cores, IPC, impressive OC capability and ring-bus low-latency connection will be probably a superbly aging cpu. Just like i7-2600k was. As a GPU the 1070Ti will best best bang for buck but wont be enough for 1440p 144hz on ultra.

I'm building a new PC rig, and I'm pretty unsure of what I should choose between these options (options below). I'm building that PC to play games at 1080p OR 1440p (haven't decided yet) @144Hz. Spend less money is good but sacrifice performance isn't good, so that are the questions: Do I need an i7, or a Ryzen 7 will be enough for 144 fps? If i7 is needed, the ~600 MHz difference between the K and non-K version is worth enough to drop from a GTX 1080 to a GTX 1070 ti? If i7 isn't needed then is a GTX 1080 needed for 144 fps (even at 1440p)?

#2

Having the option to overclock is very nice and extends the usable lifetime of your CPU.

Also, the 1070ti should be very close to a 1080, more than enough for 1080p gaming.

You can always get a better GPU with the next generation and usually for less money as well.

Build 2. 1070 Ti looks to be the smart shopper's 1080. The 8700K really isn't that much better than the non-K, but it will have better resale value, and you get to have the warm fuzzies of having "the best" for about a year before the 9700K or whatever comes out

Definitely build 2. GPUs are easier to upgrade than CPUs. The 1070ti will do either 1080p or 1440p just fine. At 1440p you'll have to drop down to high to get 144hz though.

It goes very easy, the i7 8700 is what you'll pick if you need to squeeze $ every corner and still wants as much raw performance as possible, so you'll pair it with a H310m motherboard which will be like 49,99 and use the stock cooler.

 

If you can afford more than that as in Z370 chipset and aftermarket cooling, more expensive memory, then there is no excuse not to get the i7 8700k.

Do you want to overclock(to make the CPU and GPU faster)? The choice of the builds depend on what you want to do with it. Because you given 4 choices, I would choose build 2.
