as far as memory it was cheap and i though what the hell might as well. i am going to school for engineering so i am starting to use cad programs and such.
as for the vertex 3 i have heard nothing but good things from the recent batches.
overall each computer came out to about 1600 dollars each built by myself. so in the end it was a deal i couldnt beat.
