Hi,I am looking for a mid- range RAM.I can't choose between Corsair CM2X2048-6400C5 and Kingston HyperX 2GB DDR2 1066 PC2-8500.Both are priced identical in my nearest dealer.My motherboard is Intel DG31 PR and CPU is Core2Duo E7400.RAMs from other manufacturers are not easily available in my region.Please advise.
