I have a server motherboard which has an onboard graphics chip that performs quite slowly. I would like to get a pci or pci-x graphics card that can do a little better in the range of 50$. I googled a lot and found nothing decent. I would like something that can do at least 5 billion textures/sec. That should be reasonable as the high end geforce 8800 can do 37 billion textures/sec.
Sorry to tell you but if all your mobo supports is PCI or PCI-X then your choices are pretty limited. Also PCI cards tend to be more expensive than AGP and PCIe cards but $50 might be doable depending on what you are using it for. But first we're gonna need to know what you're using the system for before we can recommend anything ...
I haven't been able to find anything decent. Only these two cards, and the specs are awful. They do only 1 Billion textures/sec and that I think is quite low. Isn't regular 32 bit PCI able to handle more?
