I have a gateway pentium 3 500 system which i have had for nearly two years now. I have always had a 4x4x24 burner which came with the system but in the last six months it has really been crapping out on me. I am thinking of getting the 24x burner by plextor but i want to be sure that my computer and its power supply can handle it. Does anyone know if what i have right now will be enough power to repalace my burner??? I know that i will not be able to take advantage of the full 24x speed with this computer but I think i am going to buy a new computer within a year so i will be using it then too. Thanks for any help.
