I was able to run a Nivida 5500 fx on my pci mobo befor i upgraded. It is probly the best pci card you will be able to find out there. If your not trying to run graphic intensive games you should be fine. Though i was able to go from my old pci mobo and my 5500 fx to a new pci-e mobo, graphics card, power supply and case for under $400. It will run most of the latest games. Though by run i mean open. I by no means sujuest you try run graphic intensive games with this. I have been for the past year and it isn't pretty.
is one on newegg for decent price.
