What keyboard and mouse do you need to play games?

Question

Iron

Hello!
The equipment listed below is office grade, a $10 keyboard, and an $8 mouse.
Regarding the keyboard:
I play such tanks in order to simultaneously go forward, turning left (both the tank and the muzzle) and shooting, you must press at the same time:
1) up arrow
2) left arrow
3) Z key
4) space
And the fact is that all these keys together are not processed (i.e. the fourth one does not work), but if you turn the tank to the right (i.e., the arrow to the right), then everything works ok. Why is it so? How to be? Keyboard fault?
Regarding the mouse:
In games, when you need to accurately aim the sight, then if you move the mouse a little bit (1000 DPI resolution), then the sight simply does not move (roughly speaking, the computer does not care that I move the mouse), and if you move the mouse a little more, then the sight goes strongly somewhere to the side (i.e., a very sick "inaccuracy") - how can I be? Buy a normal mouse?
Can these problems be solved simply by buying normal (more expensive equipment)?
Thanks :)

Well, for starters, start riding WASD
. In games, the mouse plays an important role. And it doesn’t matter which manufacturer, what matters is which sensor is in the mouse (read about Avago, etc.). A good mouse means ~5 years of comfortable play.
The surface on which this mouse "runs" also plays an important role.
To fine-tune the mouse, make the sensitivity in Windows less, and in the software from the mouse more. In the game, also reduce. At first it will not be convenient to play, but when you get used to it, you will never be able to play like with the previous settings.
A full turn of the camera should take about 25-30 cm of the mouse run on the carpet. This should be done in one movement, and not 3-4 small jerks of 7-9 cm each.

Bought six months ago. Haven't come across anything better yet. Comfortable, massive. Typing and playing is a pleasure.
