Your mobo should support that GPU just fine, note that you'll need a 6-pin PCIe power connector on your PSU though.
I'm not sure what you mean by "VGA input". If you meant to ask whther it is possible to use a VGA monitor with this card, then the answer is yes, you can, but you'll have to use a DVI to VGA adapter, which is usually delivered with every graphics card. And even if it isn't, you can get such an adapter dirt cheap.
