Different PC builds, monitor recommendations, RAM,
Even at the highest budget the slider will allow, $2500 USD, it is still only recommending 8GB of RAM. I'm no computer expert but looking at some of the recent games being released, many of them are calling for 8GB of RAM. This is only going to increase next year no doubt and I'm not looking to spend the time hassling over how to upgrade my computer to stay within requirements.
Looking through some build suggestions on Reddit and Tom's Hardware, I'm pretty sure a budget with a minimum of $2000 USD would be able to afford at least 16GB of RAM. For me, it's less about having something good enough but rather having something that will still be more-than-great.
Not only that, but my purpose of a $2000 computer is not just for gaming. It is also for rendering in programs like DAZ3D and Poser, so an i7 and at least 16GB of RAM is probably more ideal than an i5 and only 8GB, and I'm sure $2000 USD can afford both.
I'm thinking that there could be more variety in build types that you could choose from. Instead of only one build option at $2000, you could have, for example, 3 to choose from that would utilize different components for different purposes, as I want a computer that I can use for more than just gaming on the highest graphical settings.
Also, monitors are another complicated selection for people who just want to know what to buy. There exists so many different brands and resolutions so maybe you could implement them into builds or create a separate section on the website where you recommend which monitors to purchase.
