New Computer for a New Game

Situation:
That's right I'm upgrading again. Last upgrade was my phone to an Android. This upgrade is from my old cheap ass (2 year old) Acer here, to I don't know yet... Also all prices in NZD.

By the way if you ever want to know how much something is in your monies go here. Fantastic.

Thoughts:
My thought process has been something along the lines of 'I'm going to start playing Starcraft II. To do this, I need a computer that can run it.' My current cracked version kills the computer. Also note I will buy the game. Support were credit is due. 'No space for a desktop. Better get a new laptop.' Have a couple friends who play religiously and I like RTS games so should be fun. Hopefully I can get the girlfriend into it as well.

Requirements:
I like Acer so am getting another one. But I'm not too fussy.
Must have a num pad.
Preferably more then  USB ports.
Preferably an SD card reader as well.
Current hard drive is 260Gb or something pathetic which I kept at max 10Gb free. Which is terrible for torrents and software engineering social circles. So anything over 500Gb is acceptable.
I also need a fast processor. Current is 2.1GHz which is fine. But faster is always better.
Need a dedicated graphics card. Current card is a 256Mb integrated death warrant.
And it must be cheap.

Luckily I can get $1000.00 from the government to assist my 'learning'.
Starcraft II = Software = New laptop plox?

So I'll looking to spend roughly $1500.00. Shouldn't be too difficult.
Don't mind upgrading the RAM myself but considering the other specs I'm looking for I'm not expecting the laptop to have less then 4Gb RAM standard.

tl;dr: I'm getting a new laptop so I can play Starcraft II. Awesome.


Let me know if you play or have a decent laptop suggestion.
Sorry there were no funnies in this post. It makes me sad too.
