Upgrading my Graphics card

[Megawat22]

Ok, so I would like to upgrade the graphics card on my laptop but I've run into some troubles.
1. I don't know what the hell I'm doing and if what I'm looking at is even an upgrade.
2. It's a laptop and I've heard that some models can't change graphics cards.
So, Escapists, a few of you seem quite computer savvy and so I turn to you to see if you can offer me any help. If you can find it in your hearts to help me out with picking out a new graphics card (I've got approx £100 to spend so money isn't a massive issue) or if my laptop can even accept a new card.
Specs:

Processor: AMD Phenom(tm) II P960 Quad-Core Processor
Memory (RAM): 4.00 GB
Graphics: AMD M880G with ATI Mobility Radeon HD 4250
Gaming Graphics: 1917 MB Total available graphics memory
Primary Hard Disk: 339GB Free (451GB Total)
System- Model: HP Pavilion g6 Notebook PC
System Type: 64-bit operating system
Number of Processor Cores: 4

(I think that's everything you should need, if not say so and I'll edit it in)
Thanks in advance.

Most laptops you can't upgrade the GPU, including yours (I just looked up the GPU and it's an integrated GPU, meaning there isn't any card - the GPU is mounted on the motherboard).

Upside, you've just saved yourself 100 quid.

Well that's a shame, thanks for the help though.
