Laptop For Back Track

[grant_g]

Been saving for awhile, and I've amassed $800. I want a laptop to dual boot backtrack on. The laptop that I run a VM for BT5 on right now is bad - very little ram or power.

I've always wondered these things:

What kind of power does pentesting with metasploit and the other various BT5 utilities require?

Can more power help with say an Nmap scan (is the limiting factor network speed or processor speed?)

How important is RAM? (i've always wondered how demanding metasploit is. I once read a post that it can be as demanding as photoshop, but I'm skeptical)

It's taken awhile to raise the $800, and I want to spend it wisely (and save some of it, if I can).

Two possibles I've looked at. One has a ton of power and the other not so much.

I use an i5 with 4 GB ram and it kind of just sits in it's case lol. Hardly use it. I always just run BT in a VM. But in general, more power the better.

This is what I plan to get myself,

Once I get it, I will be upgrading, the RAM to 8GB and the HDD to an SSD.

Will be loading Backtrack with no dual booting.
