Upgrading is like overclocking your computer. Everyone feels that they need the speed/leetness of upgrading.
1) it may make it faster/better. But it has the cost of killing the lifespan of the chip/gun alot.
2) It voids the warranty the second you open up the case/gun.
3) Do you really need that upgrade? It's like if you're word processing then why should you get that AMD X600, 3.4Ghz chip and 3gb of RAM? So stick with stock.
Closing statements. If it aint broke then dont fix it, and Keep the warranty just incase.
