I'm looking to buy a Toshiba Satellite C855-2HG Laptop but I'm looking to upgrade the graphics card. I've seen the Asus GTX 750 Ti OC 2GB graphics card but just want to know if it's compatible. Help!

Very rarely can you upgrade a laptops GPU and when you can you ask for it from manufacturer. So the answer to this is Simply No.

The card you have will not fit a laptop simple as that. When a laptop has its own GPU aside from integrated graphics its a modified version of whatever card it has so that it can fit into a laptops case.

For a laptop, the compatible one is the one it came with.

That would be no, no, and no

First off the graphics card you are listing is for a desktop computer, not a laptop

Secondly, the laptop you are looking at has integrated graphics (graphics chip built into motherboard or cpu) and not dedicated graphics (seperate circuit board that is attached to motherboard). On a desktop you can add a graphics card to any machine, on a laptop if it is integrated graphics then you are stuck with integrated graphcs.

Third, if you do chose a laptop with a dedicated graphics card, you can only upgrade it to a card that is also made by them same OEM that is deigned to fit that model of laptop. In a desktop the graphics cards are standardized and use the same slot, in a laptop the slot varies from one manufacture to another, and even from one model to another, so there is little room for upgrading.

Ahhh fair enough, so with laptops you can't really interchange graphics cards? I'm pretty much stuck with the graphics card that the manufacturer has put inside (in this instance a Intel HD Graphics 4000 card) ?

Sorry for sounding stupid, I'm just new to all this!

Thanks for the insight. I'll be looking at desktop computers instead of laptops then.

The only reason to buy a laptop is if you need the portability, or if you have a really tiny desk.
Other than that...you give up performance/price/upgrade potential.

Yeah, there's a PC here already but it's not built for gaming so was looking to avoid having to buy a PC and make space for it. It looks like that's the only solution though as the laptops just don't come with the graphics card needed.

Thanks for all your help
