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
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
The problem I have now is a T410 with the options I want is $1184 on Lenovo's site. However, I've found a T400 with about the same specifications (except for the processor of course) for $640. That's a $544 difference.
I can afford either. But to me it's more a question of value. Is the faster i5 worth the extra $544?
