new graphic card for my old computer

Hello and welcome to the forum maxt!

A quick google search revealed that your motherboard has an AGP 4x slot which has been superseded by PCI-Express and is very outdated...

You may be able to purchase a low profile new-ish card that has uses AGP that supports Windows 7, but chances are your PSU may not be strong enough to support it given its age..

In case you're interested, a selection of video cards that may be supported by system and is Windows 7 compatible is available here:-

Speaking of system specs, can you fill in the rest of your specs (including PSU) by following this tutorial?

System Info - See Your System Specs

Thanks in advance!

DDR2 and DDR3 refers to the built in Graphics Card memory, it has nothing to do with your system's onboard RAM support..

So yes, it should be compatible...

Do you know what kind of PSU your system uses? It's very important to know the wattage so that the graphics card won't be underpowered..

The one with the 550w PSU should be able to handle the cards that i referenced to on Newegg... The other one may require a lower specced card.. Otherwise, you're good to go!

Hope that helps!
