I am planning to buy a new computer in the near future. I was leaning towards an AMD Athalon 64 3400+, 512 RAM. I know the 64bit is overkill for now, but I was hoping to keep this machine around for a while. My question is: would it be worth the extra money to go with 1GB of ram? The site I'm buying from (tigerdirect.com) says there's no such thing as too much ram, but it sounds like they just want me to spend money. I've heard people say that anything more than 512 is overkill. Any suggestions?
