Getting the final specs together for my new comp over on new egg, Was planning on an AMD 64 3500+ but there arent any 939 motherboards available. Is the performance difference between the 3400+ and the 3500 + that big of a difference? Ive read the articles at anand and THG, but still come out undecided. Is there any reason to get 3500+ over 3400+? Thanks in advance for the help.
