The i9 9900K has an integrated GPU (Intel UHD 630) - It's enough for browsing the internet, not really meant for gaming but it can play some games at 720p. Most of the Z390 boards have built in HDMI or Display Port that you can hook up to utilize that integrated GPU. It's great if you need to troubleshoot a video card issue or if you need to RMA a graphics card, you will still be able to utilize your PC for browsing the internet and stuff. -- If that's not something you see yourself needing, the i9 9900KF does not have a integrated GPU which allows for a little more headroom on overclocking. It's only worth getting if it's a decent amount cheaper than the i9 9900K though.
There is one other option that just came out recently... That's the i9 9900KS. Each and every CPU has the chance of being better than the next, which is called the silicon lottery. The i9 9900KS are i9 9900K's that are on the top tier of the silicon lottery and they set the base clock speed to 4.0GHz instead of 3.6GHz, it's boost clock is also set to 5.0GHz on all 8 cores where the i9 9900K is set to 5.0GHz on 1 core. It comes at a premium, it's for the users that want the fastest processor out of the box with no overclocking needed.
actually wouldn't suggest a Kingpin model for the RTX 2080 Ti. Those have always been aimed towards enthusiast. I would recommend this model:
