XPS17 L702X Video card.

So I am in need of a replacement video card after only 1.5 years... seems about right for dell.

I have the Nvidia GT GeForce 555M and I see that it is soldered/integrated into the motherboard. 

If that is the case will any of these work?

Where is what mine looks like.

Is the 555M really that small to where it doesn't stand out like a normal video card?
