I am getting a gtx 780 and I only have a 500 watt power supply and the gtx 780 has a minimum power need of 600 watt so I need a new power supply and I was wondering should I get 600 watt so I can just run the gtx 780 or a 750 watt so I can upgrade other parts or mabye get another gtx 780 later on.
Also it costs an extra £10 to get the 750 watt
