Wanting to buy a laptop

[Yakuza]

What I want is a laptop that I can play the following games on
Dayz - on medium to low settings
WOW - on low settings
Vice city - medium settings
GTA IV - low settings
And that multiplayer san Andreas game - on low medium settings

Then I would also like to maybe do a lil video editing and capture card stuff with my Xbox 360

And very lil bit of beat making stuff something like garage band
Computers i was look at are

MacBook pro the 13in with 500gb
A vostro 1500
And maybe a used alien ware
But i don't know anything or what im looking for so what are some good models of them?

Also found a used gaming computer close to where i live but the guy hasn't gotten back to me yet so im not going to post it yet.

I would like to not spend more then 1000 but my friend just got a MacBook and i really like but not sure if itd be good for gaming if it is then ill spend the like 1500bucks for it

This is the one that the guy hasn't gotten back back to me on yet, and the vostro has windows 8 which im not to much of a fan of but im used to that style of format because of my lumia 900

What did you get? I think the specs that you need should be of top quality. The games that you want are a little big for a laptop.
