hi there! im going to upgrade my vc to PowerColor 5770 512ddr5 and I wanna know if it's compatible to my mobo, because i saw that 5770 is PCIE 2.1 x16. Here are my mobo specs http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail... and not really sure if my mobo is PCIE 2.1 x16. Can someone clarify this? Thanks in advance!
