I'm tired of the choppy, slow video editing response of my video editor when using my Dell laptop (Dell Vostro, I7, 2.6 GHz, 16G Mem).
I'd like to get a desktop video editor and keep my laptop for everything else.  A desktop because I think it may be more flexible and able to have more capable video cards.

Can you suggest a Dess desktop model and configuration that would be great for editing 4K video or even a link with recommendations for current hardware?

Any tips are appreciated!
