Thank you all!
(And hex, it is a pIII, my bad typing)

I am not worried about power supply, One of the two upgrades was a 250 watt supply, the other a single stick of pc133 memory, 256 RAM. Other then that, and a very few software tweaks, it is factory original. I did get the thing 4 years ago, and it has been good to me, dispite the crap I put it through. Quite frankly I can't play the Sims 2 on it as it is.

I can only get a PCI card, but adding some more RAM should help. I forget who mentioned it, but a BIOS upgrade is needed, I just don't have the 'net at home to do this. Ideally I would go for a new comp, but alas, my broke college student status rules that out..

I think I am going to go with a GeForce card... It looks like it will do the job and not cost me a bundle.

And thanks again, all of you!
