Decent Gaming Card


I'm looking for a cost-efficient yet powerful card for PC gaming. Here are the specs of my system:

AMD Phenom 2 3.2Ghz Dual Core CPU
4GB DDR2 PC6400
Biostar N68S+ Motherboard (16x PCIe Expansion Slot)
550W PSU

From what I understand, the PCIe 2.0 graphics cards are backwards compatible with the 16x PCIe slots. Can someone confirm this and explain if there is some sort of decrease in performance? Also, what graphics card would suit my system well to play games like COD Black Ops in a decent resolution?

    You should be able to find a HD 5770 for about $100 like the following....
  2. PCI-e 2.0 is backwards compatible with PCI-e 1.x slots. There will be no decrease in performance. PCI-e 2.1 cards are generally not totally compatible with PCI-e 1.x slot. Some people have had problems; the argument is that some manufacturers did not implement PCI-e 1.x slots properly in some motherboards.
