Re: **Help with Video Cards**
Well its PCI it will be able to run the games but not on high, i would look at a 6600 there around 120-150 and it will play Halflife 2 oh high and will run DOOM 3 very well. What kind of slots do you have PCI? PCI-E? AGP?
*EDIT* Nvm you said you only have PCI, well that card will run the games but not on high, that card you selected is prolly your best bet.
