I have AMD X2 3600+ (Am2) Board is MSI K9NGM (Nvidia 6100) 512 DDR-2 160 GB SATA (Seagate) //I recently used my Friend's System which is as follows: //AMD Athlon 64 3000+(754 pin) //Asrock (nvidia 6100) Model i don't remember //512 RAM //160 PATA Seagate. BUT i didn't notice any significant performance difference between them. What's wrong? I am planning to add another 256 MB ram. Will it give any better results?
