Sorry for links from different sources and no links in the second solution, but I am not asking about exact prices or where to buy it.
I wonder whether these configurations are OK
* whether all parts are compatible, (I think they are, but I am quite newbie in this stuff)
* whether some part is not bringing down performance of another one
* whether there is another configuration that is cheaper but still has as good performance
I would not bother with 2 slow zeon's. Get a i7 and overclock the heck out of it and you'll have 8 threads anyway with hyperthreading enabled.
I have no idea about overclocking so maybe I should not do that ;-) Now I try to make a configuration with faster Xeons from 5400 series, with help of a friend. I should have a space for that in my budget, as he suggested me cheaper solutions for a computer case (the one I selected is for servers).
