I am planning to buy the graphics card ATI HD3850 and a 250 GB HDD. Since the card and the HDD have PCIe 2.0 and SATA-II connectors, so I wanted to know whether the are backward compatable with the older PCIe 1.0 and SATA technology; since my motherboard MSI RS482M2-IL supports only these standards.

yup but at the cost of performance.

Not much loss..........u will get 30% increase in performance only if u haf d new RS740 chipset(or its equivalent 7xx mainstream chipset) based mobo.


And I think MSI RS482M2-IL supports SATA-II
