Computer for gaming - help please!

[theRagingEwok]

Hey everyone, I'm new here and I came here to ask if any of you helpful people can help me with a recent dilemma?

I'm currently trying to run a game which has around the same system specs of CS:S - anyway, I've put them below, here. I also have a super old Dimension XPS since 2004 and wanted to put it to good use as my older game spec PC died on me

By the way, the game is 'Crossfire' - crossfire.z8games.com/

System Recommended requirements for the game:
GeForce 6600
Pentium 4 : 2 GHz
1GB RAM

How can I upgrade a dell dimension 4600 to match it?
Is it possible?
My CPU is able.
I am about to install either 1GB or 2GB RAM depending on how much I will spend on the graphics card.
The Graphics card has 128 MB dedicated memory

Thank you VERY much for any input on this!

You have an AGP slot, so not much in the path of upgrades for this machine. Another thing to take into consideration is these old Dell machines had crap for PSU's so we will need to know exactly what type of PSU is in it to give a "decent" recommendation.

The PSU runs at 250W
I just need to know if it can handle EITHER:
1GB RAM + GeForce 6600
or
2GB RAM + GeForce 6600
or
neither

Thanks again for the help!

A 6600GT is cutting it real close.
