How does it work with the mhz? i'd like to run my ram at 3200mhz but i'm confused with all the XMP stuff

XMP are just overclocking profile for your ram module. When you buy your new ram, it will come with clock speed lower than what's written on the cover, and then all you need to do is go to your BIOS and load the xmp for that module and it will oc to its rated speed.

At stock, DDR4 RAM runs at 2133 MHz.

This is part of the basic Memory JEDEC standards/regulations that must be followed (yes, even memory have regulations that must be followed).

DDR4-2133 is also the JEDEC fail-safe standard -- which is what DDR4 runs out-of-the-box.

 

You need to enable X.M.P. to get the advertised DDR4-32000 MHz speed.

This involves overclocking the RAM, and tweaking the internal CPU settings (e.g. Integrated Memory Controller (IMC) ).

The i7-8700 (K-version I am assuming?) officially supports up to DDR4-2666, so anything beyond that is considered overclocking.

 

With overclocking, "your mileage may vary" does apply, but given how Intel's IMC is very robust, DDR4-3000+ should not be much of a problem.

It is when you try DDR4 3800 MHz, 4000 MHz .... 4800 MHz ... is where things get a little dicey.

i'm not really sure what cpu i should pick, i've been thinking about the k version but it's the exact same price as a 9700k, i'm not sure which one would be the best? a normal 8700 is about $380, a 8700k and 9700k are almost the exact same $440

So 3200mhz is pretty safe/garantueed to get to?

Yes, DDR4-3200 MHz is basically guaranteed.

 

I'd go with the i7-8700K or i7-9700K option.

Is this PC more for gaming, or multi-core / multi-thread supported stuff as well?

If it is mainly for gaming, i7-9700K.

If you have programs that can use the extra threads, get the i7-8700K.

Mostly gaming but i do some video editing/photoshop, i'm not really sure which one to go for
