Core 2 Duo is faster than Dual-Core so eliminate those two.

Among the others, the fastest clock speed is the fastest CPU since all are
Core 2 Duo with the same FSB and cache.

The T7300 2.00 GHz Core 2 Duo will be the fastest since it has the most cache
and is only slightly behind the 2.13 GHz T6400 in clock speed. I don't think
you'll see any difference at all except in benchmarks with this group, though.
Other factors such as speed and amount of RAM, hard drive speed and graphics
chip will probably be the ultimate deciding factor.
