Old Game Question NR2003

I have a bud of mine who saw me playing some Nascar Racing 2003 online and my pc is really overkill for the game. He really wanted to play the game but his dell only has onboard graphics from ancient times. So I was wondering what the cheapest graphics card that could run this game maxed out. Only info I could find are the min specs,

requirements Windows, 450MHz Processor, 64MB RAM, 16MB Direct3D compatible video card, 8X CD-ROM

how old is his pc? does it even use PCI-E? Or is it AGP? model number could probably help us out.
