if i were you, i would go for the AMD64x2 which around 6k and stable pa iyahang socket for the upcoming years.
unlike in the intel class they are always upgrading like around the s478 to LGA775 to G33 and to P35 and right now naa na say bag-o which is the x series..
Also i am not discouraging for the intel class.
So the choice is up to you!
