i need to know the pci-e version of my motherboard............some people say that it has 1.1 and some people say that it has 2.0 which version it have.....i want to know this because I am going to get a radeon hd 7750..if it's a pci-e 2.0 but if it is older than this version then I think that i have to buy a nvidia gtx650 instead of the radeon hd 7750 cause amd hd 7700 series graphic cards have compatibility issues with older pci-e versions
