IMHO, filters for all quantities should be selectable via a slider, rather than a set of tickboxes. Most are, but some like graphics card RAM, use tickboxes.
It's very unlikely that someone wants a graphics card with either 4GB or 8GB of ram but not 6GB.
The quantities are also not sorted in numerical order so you have to read every one to see whether you want to tick it. This wastes time for the users.
This also applies to monitor resolution (and maybe size and pixel density). You'd need at least two sliders, height and width, but you could also have min-dimension, max-dimension and pixel-count.
I think I mentioned this before here, but that was probably when the old forum was up.
