I have a problem. I am building a gamming PC for myself. I want to spend under $3,000. I know I want the AMD 64 4000+ but I don't now which one. Bceause they have the Clawhammer chipset and the new Rev E San Diego chipset. The San Diego is a 90nm CPU which is good but the Clawhammer isn't. But the Clawhammer is more $. Which one is better for games and what CPU cooler cools a CPU the most and isn't Vaporchill or liquid cooled? Also what memory is best for games because I have found it difficult to find an answer on this. I want it for games mainly and to be 1GB. I am also going to be using the MSI K8N SLI board. And I have two more questions not related to this exact forum but I thought I might as well get all my question in one thing. Which case is best for air cooling? I was think Li-Lian PC-v1100. And what aftermarket air cooler is best for one 7800 GTX? Well thanks for the help.
