Basically what DruggedPanda said, currently GPU prices are so ridiculous that 1k build might not even be able to run latest games. At that price point your only reasonable option is to get a decent used rig if you have a tech savvy friend that can evaluate it for you. If you're absolutely set on a new build that's also around 1000$, camp on price comparison websites and look for 30% and over in discounts.
