Hey Clay,
by coincidence, I just answered to the same question this morning, see here
You would not forcibly want a laptop, often a desktop PC has better performance for the price and servicing in case of defects or upgrading is much easier
I would not consider a computer with less than 16 GB RAM as really usable for graphical desktop applications.
But of course this is not the right forum for this, as which computer to choose, new or used, and which operationg system to run, is a very vast field.
