Lmao, you got stuck with a crap Dell dimension 3000 too? What a terrible machine they produced. I guess its alright besides the fact it only has PCI slots for graphics card. I have one, and am currently building a new computer because I can't stand these crappy PCI graphics (BTW, my new motherboard should be here on Thursday probably!)
Anyways, neither of those cards are really going to let you play any games passed like 2003-2004 (if that). I got an ATI x1300 PCI that worked ok. Now they only sell the 1550's which would be your best bet. For the money you should just buy a new motherboard and keep saving up.
EDIT: forgot to mention, when I first put this card in, it was working as my main graphics even without disabling onboard. I can do 3 screens at a time if I want and not have any performances.
