I just bought this Mobo- Asus A8V-E SE Socket 939 PCI-E,SATA-RAID NEW Now I am lokking at 3400+ CPUs and I came across this- NEW*AMD Athlon 64 3400+2.Ghz Newcastle 939 Processor. this is my first AMD machine and my first one that I will build myself. I just am confused about the 'Newcastle' name. I suppose its a brand name like Prescott is to Pentiums. So any input or adice on these two items would be great!
