Also, the builds should be listed with their build date, the date the build was last edited.
It would be handy if earlier versions of the build could be linked too. You could give the build a version number which might also indicate how long the build has remained. For example, v 19.08 could indicate the spec was decided in 2019 in August.
With 'Gaming' builds, I'd like to see a move away from $xxx builds altogether, to more intuitive resolution led builds, i.e. 1080/1440/4k builds using a representative suite of games and a focus on getting the biggest bang for the buck.
problem there is that Resolution / Price / Quality is pretty similar to the old price, quality, time triangle rule of thumb
Replace time with Resolution and there you have it, two are always achievable, want to play 1440p on an RX 580, no problem... but quality settings will suffer... Want to game at 4K Ultra? well then the value aspect is out the window.
Since folks need to buy the kit and that at the end of the day will be the deciding factor for 9/10 builders its probably most sensible to keep it cost based.
Although in each build it does tell you what it's gearing for detail and res wise.
