I have an HP a6130n Computer with a ECS MCP61PM-HM (Nettle2-GL8E) motherboard. I was gonna buy a Sapphire 4650 HDMI card which only has 2.0 which I know already works since my current card is 2.0. However people are recommending I go with a higher card. I'm gonna buy a higher PSU so no problems there its just that I don't know if 2.1 will work with my computer.
