dont convert $ = 50xRs…
kmd rate is $x70Rs
as for the topic…
u donot require pci-e 2.0 x16…the card will work just fine over pci-e x16
look for p45 boards from msi in that price range…or try getting use p45 asus/gigabyte from market section.
save cash n settle for a cheaper board incase u wont be using all features.
