Can I upgrade the graphics card in my All in one PC?

I've been looking at getting GTX 750 ti graphics card and I was wondering if it would be compatible with my computer and how would I do it

My computer is: http://www.currys.co.uk/...html#packs

No… Neither the GPU nor the CPU are upgradeable in AIO computers. They are nothing more than laptops mounted to the back of monitors. They have the same restrictions as laptops!

@geek-in-training you can upgrade laptop graphics cards 4Head. You just have to make sure its provided enough cooling and its compatible. Its the same for AIOs
