Since my laptop of several years has finally decided to call it quits (I suspect motherboard failure or some sort of power failure), I've decided to start shopping for a new one.
One set of laptops in particular have caught my eye - the Sony Vaio NW series. They have two models available from the Sony site, the NW 180J and the NW 130J. The 180 is about $150 more expensive, with a few differences: it has a blu ray player (which I won't use), a slightly larger hard drive (I have several external ones already, space isn't an issue), and a different CPU.
The 180 has an Intel P7350, which has a clock speed of 2.0GHz, a front side bus speed of 1066 MHz, and a L2 cache size of 3MB. The 130 has an Intel T6500, which has a clock speed of 2.1GHz, a front side bus speed of 800 MHz, and a L2 cache size of 2MB.
Both are dual core with a 64-bit instruction set.
I intend to use the laptop to play some games (though I'm not a hardcore PC gamer). I will also be doing a lot of programming on it, so being able to handle an IDE plus a browser is important, primarily IntelliJ IDEA, which can be pretty intense on resources sometimes.
I am curious to know how big a difference a slightly slower clock speed but faster bus speed and larger cache will make, and if it's worth the extra money just for that difference. Also, as a purely aesthetic note, the 180 only comes in silver, which I don't like that much.
