Pci-e 2 graphic card on pci-e 1 motherboard

[hhf]

hi!
I have a AMD x2 3800+ processor, 2 gb RAM and Asus M2N-X motherboard with PCI-E x16 1 slot and i want to buy a PCI-E x16 2 graphic card (Radeon 5570 or Radeon 5670)- budget limited.

Given that the motherboard is a PCI Express x16 1 and the graphic cards are PCI Express x16 2 is worth buying radeon 5670 which is more expensive than the Radeon 5570.
Will i be able to enjoy the full power of the graphic card with PCI interface Express1?

Hi,

While you can use a PCI express 2.0 card in a 1.x slot, it will not be able to run at its full potential because of the bandwidth restrictions of the older slot on the motherboard. You may want to go with the 5670 though if it is not too much more money in case you upgrade your motherboard in the future. It has a faster clock speed than the 5570 does and GDDR5 ram instead of GDDR3. Other than that, I believe they are essentially the same chipset.
