Hello I am wondering if I should overclock my Sapphire Dual-X R9 270 OC 2GB to get more performance out of it. I heard that you can overclock the R9 270 to the same speed (about) as the R9 270X, is this true? And should I try overclocking my R9 270? By the way I will be using it for gaming at 1080p and my motherboard is an MSI A78M-E35 motherboard if that matters.
