I think the Athlon 4000+ is a little too expensive but how much do you think the 512kb of L2 Cache will affect preformance compared to the 1Mb on the 3700?
Also: Should i get Registered or Unbuffered RAM? I've heard it is mainly for lots of ram (Servers), as of now i'm only planning to get 512Mb (later i'll upgrade top a Gb) so do i need it?
