intel system $600
 

here is the INTEL budget system:

CPU Intel Core i3-2100 Sandy Bridge 3.1GHz 2 x 256KB L2 Cache 3MB L3 $125
NOW this may only be a dual core but it has kept up with the 955 , in tests, because it has "hyper threading: that simulates another 2 cores, if you look here http://www.tomshardware.com/reviews/...t,2859-10.html you will see what I mean, this is a base to start from because you can add a i5 2500k later if you want (once the prices come down)
