I want to put a faster CPU in my Compaq 7151WM (WM stands for Wal Mart). store on ebay has a kit (PowerLeap 423 socket to 478 socket adapter, fan assembly, and CPU - 2.5 ghz, 2.6, 2.8, 3.0 ghz -think i'm gonna get the 2.6GHz). my computer (according to my Nero Info Tool) is, "CPU - Pentium 4 1400 MHz, bus speed - 100 MHz, Motherboard - Intel D850GB, Bios - Intel GB85010A.18A.0066.P15.GB85010A.1 , memory - 768 MB ,system - Compaq Presario PC ). guy says i have to use a 400MHz front side bus chip (which he is going to send me). If i purchase this CPU and kit, then install, is my computer going to blow up? i am running Windows XP home, service pack 1 (i have all current XP updates). He says you reach the point of diminishing returns with the faster chips (2.8 , 3.0, etc.) because of the expense vs/ other limitations of system, though he will sell them to me. What do I need to do for install? Is it worth the money? around $200 (for 2.6GHz) for everything including shipping, new chip, adapter, fan assembly. it's worth $200 for me not to have to set up a new computer - if this will speed my computer up. ps. when i go to task manager, my CPU usage peaks out (%100) when i'm doing a bunch of stuff.. THANKS!!
