Replacing my laptop graphics card? :/

[kirstycakes]

Hey

Well basically, my laptop is a Toshiba Satellite L500-19z
My graphics card is a crappy Mobile Intel series 4 family chipset.

I originally bought the laptop at Christmas (2009) for everything: Social Networking, coursework, a little gaming etc. But at the time I didn't think it was rubbish for big games (such as Dragon Age: Origins).
So anyway, I was wondering if it is actually possible to replace my graphics card?
I'm looking at the PNY NVIDIA GeForce 8400 GS PCI-E Graphics Card, but is that even compatible with laptops?

My game is quite laggy, it's OK 50% of the time but it gets quite annoying when you're trying to battle and it takes about 5/10 seconds for an ability to actually work (if it even does!)

Are there any graphics cards out there that I can use? Or can I even replace my graphics card, or increase the performance of my game?

Thanks in advance

Unfortunately you can't upgrade the GPU in that laptop. You are stuck with what you have.

gurusan is correct. You can not easily slip in and out laptop gfx cards. Even dedicated ones are hard to find but by the same model.
