I need advice from you gurus. I haven't put a computer together from the ground up in a long time and I need another complete system. I was thinking about AMD since it's so cheap. Is it still cheaper to buy a prebuilt than build it yourself? Also, what's the deal with DDR RAM - should I wait to buy a system that has this? Also is there any reason that a larger Intel investment is worthwile (for similar performace)? Finally, where's a good place to buy an AMD system besides Gateway? Sorry for the newbieness of my questions, and I really appreciate you reading this all and giving me a bit of your wisdom.
