Windows 7 - Video Card Upgrade Help

Hello all,
I am looking to upgrade the video card on my computer.
It's an Acer X3910. It's a small form factor case and the
video is on is on the motherbord. I'm trying to play some
games on my computer but my system is lacking on good
Video card. I have attached information aout my computer.
Any help will be appreciated.

Could not upload service manual but here is the URL:

(Note; in the attached service manual they mention
some cards, but None of these are available on the
internet)

The nVidia cards listed are ones that aren't available at retail. I'm not sure what the retail equivalents are, but they may be equivalent to Geforce 210 and 220 cards.

Versions of the Radeon 4350 listed are readily available.

They are all low-profile low power cards.

As the X3910 has a 220W power supply, you don't want to ask much of it. You may not have an easy option to upgrade that power supply, as small form factor machines like this one don't use indsutry standard ATX style PSUs.

Making the X3910 into a tolerable gaming machine may be difficult. It wasn't built for that purpose.

Thank you for the information.
I didn't think about the PSU.
Going to look into your recommendations.
I wonder if I could upgrade The PSU ?

Thanks again.
