A decent Intel Core i7 CPU is a minimum, but Core i9, AMD Ryzen or AMD Threadripper are the best choices. If you plan on using H.264 / AVC and HEVC camera media, your CPU may be doing the decoding before your GPU even gets involved.
Read more about this in my article XAVC / XAVC-S / H.264 / HEVC and DaVinci Resolve.
At least 16GB system RAM is a minimum for any laptop or desktop you are considering. I recommend 32GB.
