video cards for a Compaq Presario CQ5205Y

A lot of pre-built systems come in different configurations. Can you run a program like Speccy to get some detailed information about your system? CPU, memory type and amount, and if you can look inside the computer and read the label on the power supply to see its wattage rating(ie 300W or similar) would be the relevant things.

it has a 250 w power supply. I am running windows 7 Ultimate 32-bit OS, 2gb ram, I have already updated to a nvidia geforce 210 but I want to be able to use 3 monitors since I have multiple monitors. I have already found a new power supply for 400 w and thought this video card might work.....EVGA GT 710 1GB DDR3 64bit Single Slot, Dual DVI 01G-P3-2716-KR
