Is this a PCI, PCI-E, or AGP?

GeForce 6150SE nForce 430

That is my current graphics card, looking to upgrade to play MW2, and I need to know whether it is a PCI, PCI-E, or AGP.

I've typed it in on google, and it doesn't really give the information I need.

If you need any more information then just tell me.

Here's my computer: http://h10025.www1.hp.com/ewfrf/wc/...en&cc=us&dlc=en&lang=en&cc=us&submit=Go%20%BB

Thanks.

 

It's PCI-E.

Check from http://h10025.www1.hp.com/ewfrf/wc/...ry&lc=en&dlc=en&cc=us&product=3662020&lang=en

And if you wish to upgrade, make sure your PSU (Power supply unit) is good enough.

 

DO IT. I made the mistake of not checking this and my PSU blew after a few weeks.

 

How can I make sure my PSU is good enough?
