Hi, I am new to the gaming pc world and I would like to ask if someone could please tell me what my psu is on the basic x51 alienware is... it's the 700 dollar one with an i3 processor, gtx 645, 6gb of ram. I don't know what the psu is and I'd like to know and know what is required for the gtx 670, the 670 is what I want to upgrade to, what do I need to run the card?
