I'm in the market for a laptop, and pretty set on getting a Lenovo T series. However I'm debating if I should get the newest (T510/T410) model with an i5 CPU or save some money and get and older model with a Core 2 Duo CPU such as the T61, T400, or T500. Is there something super special about the i5/i7 processors?
For example if I got one of the newer models I would most likely get the i5-520m with the following specs
i5-520m
2.5GHZ, 3MB L3, 1066mhz FSB, 35w
For comparison I could also get an older model with one of the following Core 2 Duo CPUs
Core 2 Duo P9500
2.52 GHZ, 6MB L2, 1066 FSB, 25 watt
Core 2 Duo T9400
2.54 GHZ, 6 mb L2, 1066 FSB, 35 watt
They are all dual core running at ~2.5GHZ. Will the i5 still be much faster then the Core 2 Duo's?
