well mr metal, usually the white slots are pci; you could put a pci vid card in it, but still pci cards are kind of weak. Brown slots are agp, agp slots are more powerful -- you want agp. You could always buy a new system, but then you are forever enslaved by "the man". Have you considedered parting out your existing machine? You can knock together a powerful system for around $500-600. You can even build a new one from scratch for less than $1000. I have not bought a pc since the early Pentium days. I say, throw off the yoke of oppression and build your own! Then you have in-home tech support 24x7!
