We picked up a few probooks (refurbs) for under 300 on groupon and that are i5 albeit an old gen model. For my brother we changed the HDD to SSD because it was just not comparable to what you expect today in performance. So I expect the same here. It's an OK machine, just plan on SSD and more RAM if you can't stand the delays.
So I want to get a new laptop Just for general use nothing fancy its the Probook 450 G5 2RS20EA it has:
500GB HDD 7200 rpm
4GB DDR4 2400 MT/s (Might upgrade to 8GB)
Intel UHD 620
