i am hopeing that when i get some cash i'm giveing my computer a mighty upgrade. I was told that the amd64fx is one of the most powerful processors and is especially good for gameing. So i went to check prices and found alot of different versions (diff mhz) that cost a bundle. what got me thinking was i saw one, the same power as mine (i have a AMD Sempron 2600+, runs at bout 1.8 and the one i saw was the same mhz 1.8) except it had alot more fsb and higher bus speed. is it these 2 things that make it run so much faster?
