Okay, I've done some shopping and I wonder what you think of this laptop for CaptureOne (I haven't purchased)
Dell - XPS 15.6" 4K Ultra HD Touch-Screen Laptop - Intel Core i7 - 16GB Memory - 1TB Solid State Drive:
Hard Drive Capacity 1000 gigabytes
Hard Drive Type Solid State Drive
Operating System Windows 10
Processor Brand Intel
Processor Speed 3.5 gigahertz
Processor Model Intel Core i7
System Memory (RAM) 16 gigabytes
Screen Size 15.6 inches
Hi Mary,
That should be a useful configuration for tethering (the 16GB memory helps), and for some postprocessing (although a larger display helps for that). I assume that as GPU it uses an NVIDIA® GeForce® GT 750M 2GB GDDR5, which is a moderately capable one (faster is always nicer, but the choices are usually limited in a Dell configuration), and I assume that Capture One can make good use of it, since nVidia GPUs are usually the best supported ones with frequent driver updates if necessary. The XPS line of machines are usually decent machines.
Here is a useful list of GPUs, with a ranking, which may be of use when you are given a choice.
Cheers,
Bart
