Actually no its a good question. The problem is that the difference is not that black & white.
I've been here since god made dirt ok.
I've had 2 new computers in that time.
The first 6 months rocks. Your fps are high, connect is silky smooth, its much easier to get on someones 6 & stay there till hes dead.
The next 6 months are also good, but there are some who have gotten faster than you.
No computer vs computer advantage, your both fast enough that it comes down to pilot.
1 year later, computers getting older.
Good time to reformat & reload. Cut out all the crap, make sure your booting clean. Half the arena is running slick new machines that are faster than you.
It gets harder & harder to keep up with whats happening in a multi con enviroment.
You find yourself flying cannon armed AC more because you don't need a 2 second burst to kill.
18 months
Computers getting obsolete, your frustrated with how you fly, can't seem to keep up. Start driving ground vehicles, goon, buffs more.
They just are not as dependant on speed.
Your counting down the months till you can afford to upgrade. (and counting the dollars available to do it too)
Wiishing just once you could afford something thats going to be so fast that you'll get 2 good years out of it instead of 1 + or 18 months, or whatever.
The last couple months your down in the slowest 10% of computers in AH.
You spend more time researching motherboards than flying.
You haunt the hardware & software forum 3 x a day.
Then the day finally comes, LIGHTING in a box, and your king of the world again.
For a bit anyway.
Seriously, it makes a difference, but nothing even close to the skill differences between pilots.
But it is the one thing that money can do to give the good pilot an edge.
