Can I update my graphics card?

Hi everybody, I have an Acer computer with an 946GZ chipset its video ram is 256mb which is a decent amount along with 2GB of RAM with dual processors. The problem is that, I can't play any games like battlefield 2 because it doesn't have Pixel shaders, or anything I downloaded the latest drivers but even that didn't fix it.

My question to you is Can I upgrade it with a simple video card like NVidia or something? or would I have to change the whole motherboard because it is a chipset? thanks in advance...btw it's bus interface is PCI I assume that this is the graphics slot what card would you recommend also would there be any problems with uprading thanks in advance....

ok, I will open it up and take a picture because to be honest I don't know the exact CPU type and other things that are needed so maybe you could identify the perfect video card or equiptment that I need to upgrade it....

Ok I got some pictures, and the information from CPU-Z as you requested here they are...

So is it possible to upgrade or not

250W PS I believe.


Finding a decent card to upgrade to with that will be.....irritating.

so now what do I do guys??

@ ultraslan1988: The MB has a PCI-E x16 slot, so that's OK.
Take a close-up shot of the PSU label, I can just see the ratings below the FSP logo but cannot make the figures out.
Why the upgrade? The reason I ask is that for HD or even normal video playback you can install a HD4550 (ATI) or 9400 (Nvidia) without problems, right now and see an instant improvement, but for games the upgrade will need to be more powerful, which my require a PSU upgrade.

I do not think either of those PSUs are suitable, they're both unknown makes and neither has a 8-pin motherboard connector, which I think you'll need-I would VERY strongly advise you to avoid them like they had the Plague and Man Flu.
The HD4650 draws a tiny amount of power, directly from the motherboard. I would say that it would run on your existing PSU (at maximum draw it takes 40Watts-less than 4 amps). It might run BF2 and GTA IV but it is a low-end card, do not expect it to run them at high settings and resolutions.
Ignore the 6200, you'd be better off sticking with integrated.
