My God. Id love to have a £3.5K budget on a new pc!
When you have 24GB of RAM you look at things differently though... that's more than enough space in RAM to mount a ramdisk (ramfs or tmpfs) and do your work in there. For example say you're working on some document, you could mount the directory it's in to RAM, then all the auto-saving etc. is done in RAM, and similarly you could get rid of the swap file and have the word processor also loaded entirely in RAM.
The net result of doing all that will be SPEED! Your whole editing session doesn't ever touch the hard disk, so it doesn't have to spin up.
In fact you could probably do the above with only 8GB or 4GB. With 24GB you could seriously think about loading the entire OS into RAM, and only using hard disk storage for persistence at the end of the day.
This is a thought, but you may end up wearing that RAM out incredddibly quickly![]()
