What are the differences between the i7 and Xeon lines of processors from Intel? More importantly, which one is better for trading? They appear to be identical. For instance, when comparing the specs of the i7-920 and the Xeon 3520, the specs indeed do come up identical. Does one processor meet the needs of a trader running 4-6 monitors better? One other note, Dell only offers the Xeons with it's T3500 machines. If you want an i7, then you have to go with the Optiplex. Thanks in advance.
