I am getting a new laptop. The performance of Octave/Matlab is affected by processor and RAM?

So, may i know, which of them affect more? The processor or the RAM? Does the performance from i3 and i7 have great difference?

Adding more RAM to your system is far less expensive and really easy considering an upgrade of a CPU.

Tipically 3-4 Gb of RAM are the right amount for a modern and "all-round" computer, an i7 is a waste of money if you are not going to use it for really intensive calculus like rendering or phisics simulations.

If i was you i will buy an i5 with 4Gb of a really good RAM with low latency, also remember that a good system comes with a good air-flow, a good and clean power source, and a good balance between the elements, if you have a really good CPU but a really bad chipset you are facing a really unpleasent bottleneck.

I am using the laptop to solve NP-hard problem. Is i3 enough? – user33831 Nov 20 '11 at 9:52

Then an SSD hard drive.

It all depends on what you'd be doing, but if by any chance you'd be loading large datasets then your first priority would be RAM.
