Yeah that 5700 does seem like a great card that Eastern Digital selected, trust me.
It is rather expensive though i'd think for a PCI card, but reviews say it can run Doom 3 at 800x600 and this seems great to me for someone who can only update to that interface
...I guess it isn't really that old a card really.
As for ones on that site...it only lists 3 PCI class cards in the Video Card section and I don't really know how good they are. Again, they seem rather expensive... especially since a 9200 class card won't be half as good as a AGP or PCI-E card's at 9600 or higher and seems nearly the same price
I'd seriously consider getting a good one for a system that old if you don't want to go updating everything
As for Eastern Digital...why has his account been disabled?...
