johnny is perfectly right, if you suck you suck
Better equipment mostly makes a difference for advanced or pro players, but at amateur level it's not that big a deal UNLESS as Vaskez stated correctly you are using lowest quality which will affect you even at novice level.
Compare it to online-shooters:
If you play counter-strike on a P90 with onboard graphics your game will lag and you will suck!
If you play it on an adequate system you can rise high if you have the talent.
Once you get to the pro level even such little things as improved mousepads will be able to give you a further edge over other players as talented as you. But better players you won't catch even if your system is high end and your mouse glides on a hoverpad
