So I've had this thing for over 2 years now, and ever since I got it, It has been lackluster at best. I'd like to know what the possible upgrades that I can make for this laptop. If you can, please list the best GPU, CPU, etc that I can upgrade to, if I can use sli, etc. Please don't link me to other threads and please refer to components and such in a simple way, I am only a humble laptop user curious at possible upgrade possibilities. Here are some of my specs:
GPU: Nvidia Geforce 9400
CPU: Intel Core Duo CPU P8600 @ 2.4GHz
BIOS: Ver A02 1.00PARTTBLZ
Thank you in advance.
