Starting at $699, it's going to be hard to find a more affordable gaming laptop than the Asus TUF Gaming FX504. For the price, you get an 8th Gen Core i5 CPU and a Nvidia GTX 1050 GPU, which is enough to play most games on low or medium settings. Keep in mind that such a low price point, means that some sacrifices must be made. But if you want to spend as little money as possible for a gaming rig, the FX504 is the way to go.

A few less common items are worth looking for if you're a serious mouse tweaker. The software might control "lift distance," or how far you can raise a mouse off the pad or desk before it stops tracking. A slider or, better, a wizard-style setup function will dictate this in the utility, if present. Another feature is surface calibration, in which the mouse software runs a routine that optimizes the mouse and its sensor for the texture and traits of your mousing surface. On the even more esoteric side: support for angle snapping (a movement-compensation feature that helps you move the mouse in straight lines) and for designating different resolutions for the X and Y axes (say, for faster tracking only sideways, to traverse a vast landscape in an RTS world).
