If not then suggest another card around the same price range as the 6790.My Rig is a
i3 530 2.9ghz
400w power supply(going to buy a new one along the card)
I would be very nervous with a 400 watt power supply when using a card as potent as the 6790. I'm guessing that the minimum wattage should be in the 600 watt range. You know what can happen, with the system, when you start stressing the power supply.
