Graphics Card Question



*I posted this in the Nvidia category because i did not see the general graphics card category, I apologize.*

Hello community, I just got a laptop for christmas, and everything about it is real swell, except for the graphics card.

My Laptop is an HP 2000-2b20NR
With an Intel(R) Pentium(R) CPU B980 @ 2.40 Ghz
With 4GB Ram
WIndows 8 64 Bit
GPU: Intel(R) HD Graphics Pixel & Vertex SHader at 4.1, with 32MB VRAM(This is the part i need to upgrade.)

So, i was looking into purchasing a new graphics card, i.e. an older GTX like the 560 or something.

I don't know much about computers, but after some searching, I found older articles indicating most laptops cant have their graphics cards changed/upgraded.

If my laptop could be upgraded I was planning to take it to bestbuy for installation, since i'm not really a DIY guy.

SO the only question I have is, can my Graphics Card be upgraded, and if so, what cards would my laptop be compatible with?
