Random tech tip: If you need a Windows laptop on a budget, consider a used Lenovo P series.

15-inch models were called the P50, P51, P52 and P52 (then the switched the name to P15, but they aren't cheap yet).

17-inch models were the P70, P71, P72 and P73 (same deal for the P17).

They're powerful, highly upgradeable, have extremely good build quality, and they are available for a very good price. These are better than many new computers at 2x or 3x time the price.
