So I have a simple question. I'm very very interested in getting the GTX 560 ti 448 and I wanted to know if my power supply had enough watts. I saw on one product on newegg that it said a minimum of 550 watts. (http/www.newegg.com/Product/Product.aspx?Item=N82E16814130739) that's the card I want. My power supply is 530watts so according to what is listed on that product I'm 20 watts short. Will I have issues power wise with this card or in reality is 530 watts enough? If it based on what other parts my PC has, I'm running an AMD Athlon II x4 630 processor 2.80GHz, 4GB ram, Windows 7 installed on a 750GB HDD and a 60GB SSD.
