Two Laptops, Which one?

Hello,

There are two laptops I have found, but I only want the best one.

One has:
ATi Mobility Radeon HD 5870 GPU
i7 720QM CPU
12GB of RAM.
($2,300 AUD)

The other has:
GTX460 GPU
i7 740QM CPU
8GB of RAM
($2100 AUD)

So which one should I get?

Purpose for the laptop? Both are overkill for school or business work.

Well I will be using it for uni, but I want the grunt for my games (WoW, CoD, Crysis, etc) as well and for it to be able to handle applications like Sibelius and Cubase for my music recording/editing.

Edit: As far as I can tell, the first one has a better GPU but a weaker CPU and vice versa for the second one. I want to know whether it is better to sacrifice the small CPU difference or the GPU difference. The 5870 is a fair bit better than the 460M, but the CPU does affect the GPU performance.

Here are some gaming benchmarks for comparison:

Something to keep in mind. Those benchmarks might have been done with 1366x768 resolution LCDs so something that looks playable at Ultra is likely to need to run @ High on 1920x1080 LCDs to get fluid & smooth performance.

You can get an estimate from one of the sites that ship internationally like Xotic PC.
Additionally, they have the new Sandy Bridge CPUs available as well. And you get to choose optional configurations.
They're also showing a MSI laptops, along with Asus and Custom Sagers.
