Upgrading and worried about compatibility

[Arsinos]

I just got into playing Neverwinter nights 2 with some friends and when i installed a copy of it onto my dimension i was shocked to learn i have a crappy video card that cannot play it. So im upgrading. Im not the best with computers, i can install most of my own hardware, RAM is easy, but i have no idea what type of video card my computer can handle. The specs of my computer as far as i know are;

Windows XP
Dell Dimension DM051
Pentium D 2.66 ghz
0.99 gb RAM

Current video card: Intel(R) 82945G Express Chipset Family

If more imformation is needed ill gladly provide whatever i can. Thank you in advance for your time.

System Model: Dell DM051
BIOS: Phoenix ROM BIOS PLUS Version 1.10 A07
Processor: Intel(R) Pentium(R) D CPU 2.66GHz (2 CPUs)
Memory: 1014MB RAM
Page File: 404MB used, 2037MB available

This is just some different information i found around my PC, dont know if it helps or not

It all depends on the slots in the motherboard. They will either be AGP, PCI or PCI-Ex slots. Your existing VGA device is part of the motherboard.
As far as I can find out, it has no AGP so you are really limited to a PCI-Ex card.
I don't know which country you are in so cannot recommend a source, but there are loads of them - performance relates to price!

Country

I live in the Unites States sorry, forgot to post that part. Is there a way i can find out what slots i have open for a video card? I know there are some open slots in my computer but Im at a loss as to what they are for, any help is much appreciated.

As above - you have only PCI and PCI-E slots. You need to run a PCI-E graphics card. You could either take the machine to a local shop and pay a bit more for the card but at least you would be sure it would work, or get something from one of the many on-line stores.
