http://pcpartpicker.com/p/zcwZ i never really used a Xeon before and i heard they only work with a 1333mhz ram so i used that and i'm trying to make a good workbench for a friend and i usually use a i7 but the Xeons are alot cheaper. if it isn't compatible i'd just use a i5 but the Xeon is alot stronger
so just get a h77? and xeon is equal 2 i7 a fx isn't even at a i5
a xeon is the same speed as a i7 3770, just without graphics and will run way cooler.
a fx is around the same speed as a i7 in workstation tasks, but the advantage is that it can overclock. the disadvantage is that it will run hotter and will use 2x as much power as a xeon. just a heads up.
