Hello, basically i have a computer that i originally got a geforce gt 520 to expand my desktop to two monitors. Now, however, I have the need to expand to 3 or 4 monitors or even more in the future. How do I go about doing this? Currently the gt520 is occupying the only pci express x16 slot. All I have left is one pci slot and two pci express x1 slots. What can I do to expand my desktop to 3-4 or even more computers? Thanks in advance!

Okay I am willing to spend a max of 100$ (if thats too low, prefer the lowest price above it), I dont really mind what brand I just want it to work, and the power supply is 280 watts. If it might matter, currently the geforce gt 520 is Nvidia I believe.

The specs of my machine are here:

I really appreciate your help. I've been trying to research what graphics card to get but couldnt exactly figure out what constraints and compatibilities are used to factor in choosing the right card.
